The question image/reaction scheme and the actual option structures are missing. Only the text

“The major product in the following reaction”

is provided, but the reaction itself and options $A, B, C, D$ are blank. Because of this, the major product cannot be determined from the given information.

Step-by-step analysis

1. To solve an organic chemistry product-based MCQ, we need:

   • the starting substrate,
   • the reagents/conditions,
   • and the structures of options $A, B, C, D$.

2. In the present question, none of these are visible.

3. Therefore, no chemical transformation can be inferred reliably.

Conclusion

The answer cannot be derived from the provided data. Please share the complete reaction scheme/image and the option structures.
