The question refers to "the above reaction", but the actual reaction scheme/image is missing from the prompt. Also, the options $A, B, C, D$ are blank. Because of this, the identities of $X$ and $Y$ cannot be derived from the given information.

What is missing

To solve such an organic chemistry question, I need:

1. The reaction sequence / structure shown in the question.
2. The options corresponding to $A, B, C, D$.

Without the reaction, there is no chemical basis to determine $X$ and $Y$.

Comparison with stored correct answer

The stored correct answer is given as B, but since the actual reaction and options are absent, I cannot independently verify whether option $B$ is correct.

So, with the current information, I must disagree with confirming the stored answer as solved from first principles.
