Comprehension Type

Direction This section contains 2 paragraphs, each describing theory, experiments, data, etc. Five questions related to the paragraphs have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).

Passage I

An unknown organic compound A is determined to have molecular formula C₆ H₁₂ O  and passing it through chiral column does not separate it into enantiomers. A does not react with Br₂ nor with cold, dilute alkaline KMnO₄ . Heating A with concentrated H₂ SO₄ gives product B (C₆ H₁₀ ) which can be separated into enantiomers. Ozonolysis of a single enantiomer of B produces C, an optically active keto-aldehyde of formula C₆ H₁₀ O₂ which gives positive iodoform test.

Q. 

Structure of B that satisfy the above criteria is
