The question refers to “the following reaction”, but the actual reaction scheme/structure is missing from the prompt. Also, the options A, B, C, D are blank, so there is no chemical information to evaluate.

Because of this, the major product cannot be determined from the provided text alone.

What is missing

To solve this organic chemistry question, I would need:

1. The reactant structure
2. The reagents/conditions
3. The product options A–D

Without these, no valid chemical deduction can be made.

Conclusion

Since the reaction image/options are absent, I cannot independently derive the answer. Therefore I also cannot meaningfully verify whether stored answer C is correct based on the given information.
