Solution

The correct option is D $C_{6} H_{5} - C H = C H - N O_{2}$
$C_{6} H_{5} - C H O + C H_{3} - N O_{2} N a O H - --- \to C_{6} H_{5} - C H (O H) C H_{2} - N O_{2} \to C_{6} H_{5} - C H = C H - N O_{2}$

In the presence of sodium hydroxide, nitromethane condenses with benzaldehyde to form nitro alcohol.

Nitro alcohol loses a molecule of water to form $C_{6} H_{5} - C H = C H - N O_{2}$

Option D is correct.
