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

Passage

An organic compound A (C₇ H₁₆ O) shows both enantiomerism and diastereomerism. Treatment of a pure enantiomer of A with Na₂ CrO₄ /Dil. H₂ SO₄ gives B  (C₇ H₁₄ O) - Also A on dehydration with concentrated H₂ SO₄ gives a single alkene C (C₇ H₁₄ ). Ozonolysis of C followed by work-up with Zn-H₂ O  gives D (C₅ H₁₀ O) as one of the product which gives racemic mixture on reduction with NaBH₄ .

Q. 

The structure of A satisfying the above criteria is
