The question refers to “the following reaction”, but the actual reaction scheme/image is missing. Also, the options A, B, C, D are blank in the prompt.

So, the product cannot be determined from the provided information.

Step-by-step analysis

1. To solve an organic chemistry product-formation question, we need:

   • the starting compound,
   • the reagent(s)/condition(s),
   • and the options (or at least the structures).

2. In the current prompt, none of these are visible:

   • no reaction is shown,
   • no structures are given,
   • options A–D are empty.

3. Therefore, it is not possible to derive the product from the available data.

Conclusion

Because the reaction and answer choices are missing, I cannot independently verify whether option B is correct.

Please provide the reaction figure or write the reactant/reagents/options in text, and I can solve it fully step-by-step.
