The Correct Option is
Solution and Explanation
Concept:
Aldol condensation between two different carbonyl compounds is called cross aldol condensation.
Step 1: Identify reactants.
• Benzaldehyde (no $\alpha$-H)
• Acetophenone (has $\alpha$-H)
Step 2: Reaction type.
Enolate from acetophenone reacts with benzaldehyde. \[ \Rightarrow \text{Cross aldol condensation} \]
