The question image/reaction scheme and the actual option structures are missing in the provided text. Only

• In the reaction given below: The product 'X' is:
• Options A, B, C, D are listed, but their structures are not shown.

So the product cannot be determined from the text alone.

What is needed

To solve this organic chemistry question, I need:

1. The full reaction scheme (reactant/reagents/conditions), and
2. The structures corresponding to options A, B, C, and D.

Without these, any identification of product X would be a guess rather than a valid step-by-step solution.

Comparison with stored answer

The stored correct answer is A, but since the reaction and options are absent, I cannot independently verify whether A is correct.
