The major product formed in the following reaction is 

Step 1: Understanding the reaction.
This is a reaction of a cyclohexene derivative with iodine (I₂) and sodium bicarbonate (NaHCO₃) in water. The presence of iodine suggests a halogenation or substitution reaction, and the sodium bicarbonate is likely to act as a mild base, facilitating the reaction. The formation of a product from this reaction suggests a halogenation at the benzylic position.
Step 2: Analyzing the options.
- Option (A) is incorrect, as it does not represent the expected product.
- Option (B) is correct, as it represents the correct halogenated product formed by the reaction.
- Option (C) is incorrect, as it does not fit the expected pattern.
- Option (D) is also incorrect, as it does not correspond to the expected major product.
Step 3: Conclusion.
The major product formed is shown in option (B).
