Correct answer: D

The question as provided is incomplete: the reaction scheme and the actual structures for options A, B, C, and D are missing. Without the reactants/reagents/products shown in the figure, the major compound YYY cannot be determined from the text alone.

What is missing

  1. The reaction sequence after the words "In the following reactions".
  2. The structural formulas corresponding to options A, B, C, D.

Why this matters

In aldehydes, ketones, and carboxylic acids, the major product depends critically on:

  • the starting compound,
  • the reagents and conditions,
  • whether oxidation/reduction/condensation/rearrangement occurs,
  • and the exact structures in the options.

So there is not enough information to derive YYY reliably.

Comparison with stored answer

The stored correct answer is D, but since the essential reaction scheme and option structures are absent, I cannot independently verify that choice from the given data.

Please upload or paste the complete reaction figure and the option structures so I can solve it step-by-step and check whether D is correct.
