The question refers to "the following sequence of reaction", but the actual reaction scheme/figure is missing from the prompt. Also, the options A, B, C, D are blank.

Because of that, the major products B and C cannot be determined from the information provided.

Why the problem cannot be solved as given

To identify products in haloalkane/haloarene chemistry, I need the missing details such as:

1. The starting compound
2. The reagents and conditions in each step
3. The actual answer choices

Without the reaction sequence, any answer would be guesswork.

Comparison with stored answer

The stored correct answer is given as B, but since the reaction sequence and options are absent, I cannot verify whether that is correct.

What is needed

Please provide the reaction diagram/image or type out the sequence, for example:

• starting compound
• reagent for step 1
• intermediate/product B
• reagent for step 2
• product C
• full options A, B, C, D

Then I can solve it step-by-step and compare properly.
