Correct answer: A

The question statement is incomplete. It says:

  • “Compound (X)(X)(X) undergoes following sequence of reactions to give the Lactone (Y)(Y)(Y).”
  • Options: A, B, C, D

but the actual reaction sequence/figure and the structures of options A–D are missing.

Without the reaction scheme and option structures, it is impossible to determine which compound (X)(X)(X) forms the lactone (Y)(Y)(Y).

Why the answer cannot be derived

To solve such a question, one must know:

  1. The structure of lactone (Y)(Y)(Y)
  2. The reagents and conditions in the reaction sequence
  3. The structures corresponding to options A, B, C, and D

Since none of these structural details are present in the text provided, no valid chemical deduction can be made.

Conclusion

Because the essential information is missing, I cannot independently verify whether option A is correct.
