The question refers to “the following reaction” and asks for the major product, but the uploaded prompt does not include the reaction scheme or the option structures. All four options are shown as blank:

• A:
• B:
• C:
• D:

So the actual organic transformation cannot be analyzed from the provided data.

What can be concluded?

1. To determine the major product in an organic chemistry question, we must know:

   • the starting compound,
   • the reagents/conditions, and
   • the structures of options A–D.

2. Since these are missing, a step-by-step chemical solution is not possible.

3. The only available extra information is the stored correct answer = C.

Comparison with stored answer

Because the reaction and options are absent, I cannot independently derive the product. Therefore I cannot honestly verify whether option C is correct from chemistry reasoning alone.

If you provide the reaction image or the structures/reagents, I can solve it properly and check the answer rigorously.
