Solution

The correct option is B Acetone
Acetone gives a positive iodoform test as it is a methyl ketone moiety. It does not reduce Tollen's reagent or Fehling's solution which are the test's characteristics of aldehydes.
Acetone forms a cyanohydrin with $H C N$ (characteristic of a carbonyl group) through nucleophilic addition reaction.
