Direction:The following questions consist of two statements, one labelled as Assertion and the other Reason. Examine both the statements carefully and mark the correct choice according to the instructions given below.

Assertion:Mists are non-viable particulates produced by particles of spray liquids and by condensation of vapours in air.

Reason:Herbicides and insecticides that miss their targets travel through air and form mists.
