Solution

The correct option is B Ketone
Reaction of Grignard Reagent with Alkyl Cyanide:
Step 1: Nucleophilic attack
Step 2: Hydrolysis of imine
Nitriles, $R - C \equiv N$ , react with Grignard reagents or organolithium reagents to give ketones.
The reaction proceeds via an imine salt intermediate that is then hydrolysed to give the ketone product.
