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

So, with the given information, the product cannot be derived chemically.

What is missing

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

1. The reactant structure
2. The reagents/conditions
3. The product options A, B, C, D as structures

Without these, it is impossible to determine the major product by mechanism or by option analysis.

Comparison with stored answer

The stored correct answer is C, but since the reaction and options are absent, I cannot independently verify that conclusion from chemistry principles.

Therefore, I do not have enough information to agree with the stored answer on the basis of derivation.
