Correct answer: A

The question refers to an “above reaction sequence”, but the actual reaction scheme and even the option structures are missing in the provided prompt. Only the abbreviations

  • Et=−C2H5\mathrm{Et} = -C_2H_5Et=−C2​H5​
  • tBu=(CH3)3C−\mathrm{tBu} = (CH_3)_3C-tBu=(CH3​)3​C−

are visible, while the compounds/reagents leading to products AAA and BBB are not shown.

Because of that, it is not possible to derive the products uniquely from the information given.

What is missing

To solve this, I would need at least one of the following:

  1. The full reaction sequence (substrate, reagents, conditions), or
  2. The structures of the answer options A, B, C, D.

Without the reaction scheme, any answer would be only a guess.

Comparison with stored correct answer

The stored correct answer is A, but since the reaction itself is absent, I cannot independently verify that choice from the provided data.

So, based strictly on the visible information, the problem is incomplete.
