The question refers to “the following reactions” and asks for the major products A and B, but the actual reaction scheme and the option structures are missing from the prompt.

So, at present, there is not enough information to chemically determine the products.

What is missing?

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

1. The reaction sequence / structures shown in the image,
2. The reactants and reagents written in text,
3. The actual option structures for A, B, C, D.

Why I cannot verify the stored answer

Although the stored correct answer is given as C, I cannot honestly confirm or reject it without the reaction scheme and options.

Conclusion

Please upload or type the missing reaction diagram/options, and I can then solve it step-by-step and verify whether option C is correct.
