The question refers to “the following sequence of reactions” and asks for the major product [B], but the actual reaction scheme and the option structures are not visible in the provided prompt.

Since the reaction sequence and options A–D are missing, the product cannot be determined from the given information.

Why the answer cannot be derived

To solve such an organic chemistry question, I would need:

1. The starting compound
2. The reagents/conditions in each step
3. The structures of options A, B, C, D

Without these, there is no chemical basis to identify the major product.

Comparison with stored answer

The stored correct answer is C, but because the reaction scheme is absent, I cannot independently verify whether C is correct.

Please provide the missing reaction sequence image/text and the option structures so I can solve it step-by-step properly.
