Solution

The correct option is C Condensation reaction
The reaction of an aldehyde $(C H_{3} C H O)$ with hydrazine $(N H_{2} - N H_{2})$ to form hydrazone $C H_{3} - C H = N - N H_{2}$ is an condensation reaction. The reaction is as follow:
$C H_{3} C H O + N H_{2} - N H_{2} ⇌ C H_{3} - C H = N - N H_{2} + H_{2} O$
Hence the correct option is (b).
