Solution

The correct option is C
A is $(C H_{3})_{3} C O H, w h i l e B i s (C H_{3})_{2} C = C H_{2}$ or $(C H_{3})_{2} C O$

tert - Alcohols are not oxidised under alkaline conditions because they do not have any H on C having OH group. However, tert - alcohols when heated with strong acidic reagents, they undergo dehydration to form alkenes which then undergo oxidation to form ketones
