The question refers to a reaction sequence and asks for the major product $C$, but the actual reaction scheme/structures and the option structures A, B, C, D are not visible in the prompt.

Because of that, the product cannot be derived from chemical reasoning alone: the key information needed is missing.

What is missing

To solve such a haloalkane/haloarene problem, I need:

1. The starting compound
2. The reagents/conditions in each step
3. The structures corresponding to options A, B, C, and D

Without these, there is no valid way to determine the major product.

About the stored answer

The stored correct answer is given as B, but since the reaction sequence itself is absent, I cannot independently verify whether B is truly correct.

So, I cannot honestly agree with the stored answer on chemical grounds from the information provided.

Please upload or type the reaction scheme and the option structures, and I can solve it step-by-step.
