The increasing order of acidity of the following carboxylic acids is:

Identify the product $A$ in the following reaction:
(Image of a tricyclic allylic alcohol reacting with $p$-benzoquinone in the presence of $[(CH_3)_3CO]_3Al$ to form $A$)

Compound $A$ was prepared by oxidation of compound $B$ with alkaline $KMnO_4$. Compound $A$ on reduction with lithium aluminium hydride $(LiAlH_4)$ gets converted back to compound $B$. When compound $A$ is heated with compound $B$ in the presence of $H_2SO_4$,it produces a fruity smell of compound $C$. To which family do the compounds $A$,$B$,and $C$ belong?

What are the products formed at the anode during Kolbe synthesis?

The product $(X)$ of the reaction is:
