The question asks for the major product of a sequence of reactions, but the actual reaction scheme/structures and even the option structures A, B, C, D are missing from the prompt.

So, as given, the problem is incomplete and cannot be solved chemically in a valid way.

Why it cannot be solved

To determine the major product in organic chemistry, we must know:

1. Starting compound
2. Reagents/conditions in each step
3. Structures corresponding to options A, B, C, D

Here, none of these are shown. Therefore no step-by-step reaction mechanism or product prediction is possible.

Comparison with stored answer

The stored correct answer is C, but since the reaction sequence and option structures are absent, this cannot be verified independently.

Hence, I cannot honestly derive option C from the provided information.

What is needed

Please provide the missing:

• reaction sequence image or text,
• substrate structure,
• reagents/conditions,
• and option structures.

Then I can solve it step-by-step and verify whether C is correct.
