Abstract nouns are nouns that cannot be perceived by any of our senses, like sight and smell. They're ideas, concepts and states of being. In the sentence, the italicized words 'wisdom' and 'strength' are both abstract nouns. 'Wisdom' is the state of being wise and 'strength' is the quality of being strong. They're abstract nouns, hence option C is correct. Collective nouns refer to a group of people, animals or objects. the nouns 'wisdom' and 'strength' do not refer to a group, hence option A is incorrect. Concrete nouns are nouns that can be perceived by at least one of our senses, for example, a man is concrete, but his wisdom and strength are abstract, hence option B is incorrect. Option D is incorrect because the nouns are abstract, as in option C.

An abstract noun refers to a concept, an idea or state of being. 'Cleanliness' and 'Godliness' are both abstract nouns, the former denotes a state of being clean, the latter refers to the act of being or like God hence option A is correct. Concrete nouns refer to something that can be perceived by any one of our senses, 'cleanliness' and 'Godliness' are nouns that do not have a physical existence, they cannot be perceived by any of our senses. They're states of being, hence option B is incorrect. Collective nouns refer to a group of people, animals or things, the italicized words are not collective, they do not form a group of anything as they don't refer to physical entities, hence option C is incorrect. Option D is incorrect because the nouns 'cleanliness' and 'Godliness' both are abstract nouns.

Collective nouns refer to a group of people, animals or things in a specific manner. In the given sentence, 'crew' is a group of people that work together on the ship. Hence it's a collective noun, and option A is correct. Ship is a common noun that refers to a vessel in which people travel over sea, hence option B is incorrect. Option C is incorrect, as 'strike' is an abstract noun that refers to the stoppage of work by employees in protest. Option D is incorrect because 'ship' is not a collective noun, but it's a common noun.

'Grove' means 'a small orchard or group of trees' and is, thus, a collective noun. 'Mango' and 'trees' are common nouns but not collective nouns.

A collective noun is a name used to represent a group of people, animals of things. It is generally singular in construction.

The italicized word "truth" means 'the quality or state of being true'.
Abstract nouns refer to a quality or state, hence the word 'truth' is an abstract noun.
Countable nouns are nouns that can be counted using numbers: one kitten, two apples, etc. Uncountable nouns are nouns that cannot be counted, they're usually abstract nouns (quality, state of being) or nouns that are too amorphous or small (liquids, powders, gases like milk, salt, air).
So, 'truth' is an abstract noun and also, an uncountable noun. Hence option A is correct.
Truth cannot be counted, you cannot say: You need to say two truths to me. It sounds grammatically incorrect. Hence 'truth', which is an abstract noun, is not a countable noun and option B is incorrect.
A concrete noun refers to something that can be seen, touched, smelled, heard or tasted.
A confusion may arise, when you say: see the truth. When you say that truth can be seen, it doesn't mean that truth is an object or a thing that can be seen, it refers to the realization of truth. You see (or realize) the truth in something or someone. So, 'truth' is not a concrete noun.
Option C: truth is uncountable, but not concrete.
Option D: truth is neither countable nor concrete.
Hence options C and D are incorrect.
