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

So, the problem as provided is incomplete: without the reactant, reagent/conditions, and option structures, the product cannot be derived chemically.

Step-by-step assessment

1. Identify required information for an organic product prediction:

   • Starting compound
   • Reagent(s)
   • Reaction conditions
   • Structures of options A, B, C, D

2. Check the prompt:

   • The prompt says: “Find out the major product from the following reaction.”
   • But no reaction is shown.
   • Options are listed only as:
     • A:
     • B:
     • C:
     • D: with no structures.

3. Conclusion:

   • It is impossible to determine the major product uniquely from the given text alone.
   • Therefore, the stored answer $D$ cannot be verified from the available information.

Final conclusion

The question is incomplete, so no valid chemical solution can be produced unless the missing reaction image / structures / options are provided.
