The question refers to “the following reaction” and asks for the major product, but the reaction scheme and the structures of options A–D are missing from the prompt.

Because the actual reactant/reagents and option structures are not provided, the product cannot be determined logically.

What is needed

To solve this, I need at least one of the following:

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

Without that information, any choice would be a guess rather than a chemistry-based derivation.

Comparison with stored answer

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