The question refers to “the following reaction” and asks for the major product, but the reaction scheme/image and the option structures are missing. The options are shown only as:

• A:
• B:
• C:
• D:

with no chemical structures provided.

Step-by-step analysis

1. To determine the major product in an organic reaction, we need:

   • the starting substrate,
   • the reagents/conditions, and
   • the structures of the options.

2. In the current prompt, none of these are visible. Therefore, the product cannot be derived chemically from the given information.

3. Since the problem explicitly asks to compare with the stored correct answer, the stored answer is given as D, but without the reaction and option structures, this cannot be independently verified.

Conclusion

Because the reaction diagram and option structures are absent, the answer cannot be solved from the provided data.

However, the stored correct answer is D.
