Solution

The correct option is D Nucleophilic addition-elimination reaction
The given reaction is nucleophilic addition-elimination reaction. Here, hydrazine molecules $(N H_{2} N H_{2})$ are nucleophiles. A nucleophile always attacks an electrophile. Hence, hydrazine molecules will attack the carbon centre (i.e., electrophile) of aldehyde $(R C H O)$ . When a nucleophile attacks on an electrophile, the reaction is termed as nucleophilic addition. Simultaneously, a water molecule is also eliminated in the given reaction. Thus, this is the case of elimination reaction.
