Explanation:

1. Mechanism of the reaction:
- The addition of HBr to 2-pentene follows an electrophilic addition mechanism.
- The first step involves the formation of a carbocation intermediate.
- The carbocation can form at two different positions in 2-pentene, leading to the formation of two different products.

2. Formation of products:
- When the carbocation forms at the second carbon of the double bond, 2-bromopentane is obtained.
- When the carbocation forms at the third carbon of the double bond, 3-bromopentane is obtained.

3. Conclusion:
- Therefore, the addition of HBr to 2-pentene gives both 2-bromopentane and 3-bromopentane as the final products.
- The correct answer is option 'C' which states that both 2-bromopentane and 3-bromopentane are obtained in this reaction.
