The question refers to “the following reaction” and gives options $A$–$D$, but the actual reaction scheme and the option structures are missing from the prompt.

So, it is not possible to determine the major product from the provided information alone.

Step-by-step analysis

1. To solve an organic reaction product question, we need:

   • the starting compound/substrate,
   • the reagent(s)/conditions,
   • and ideally the structures of options $A$–$D$.

2. In the current prompt, only this is available:

   • Subject: Chemistry
   • Topic: Organic chemistry
   • Sub-topic: Haloalkanes and haloarenes
   • Type: MCQ
   • Stored correct answer: $C$

3. Since the actual reaction and options are absent, any attempt to infer the product would be speculation.

4. Therefore, I cannot validly derive whether option $C$ is correct.

What is needed

Please provide either:

• the reaction image/scheme, or
• the substrate, reagents, and all option structures written in text.

Then I can solve it step-by-step and compare with the stored answer.
