Oxidation reactions can be carried out with chromic acid in aqueous acetone at 5–10°C.Which of following is incorrect in this respect (a) (b)

A solution of chromic acid in the presence of acetone is known as Jones reagent. This reagent is mostly used for the conversion of most of the primary alcohols to carboxylic acids and the secondary alcohols to ketones. Since this reagent is very selective and sensitive, it does not attack the double or triple bond so it used to oxidize the allylic or benzylic alcohols to aldehydes.
