The question refers to “the following reactions,” but the actual reaction scheme/image and the option contents are missing in the provided prompt. Also, the options are listed only as:

• A:
• B:
• C:
• D:

with no structures or names.

Because of this, the products $A$ and $B$ cannot be determined from the given information.

What is missing

To solve this, I need:

1. The reaction sequence (reactants, reagents, conditions), and
2. The actual option choices showing possible products.

Conclusion

Without the reaction scheme and option details, it is not possible to derive the products or verify whether option $D$ is correct.

Please upload or type the complete reaction diagram and options, and I can solve it step-by-step.
