- 1.21 times, same
- 1.1 times, 1.1 times
- both remains the same
- 1.2 times, 1.1 times

The Correct Option is A
Solution and Explanation
When a wire is stretched, its resistance and specific resistance may change. Let's analyze each option to determine the correct answer:
If the new resistance becomes 1.21 times and the specific resistance remains the same, this implies that the wire's length increased while its cross-sectional area remained constant.
Therefore, the correct answer is: (A) the new resistance becomes 1.21 times and the specific resistance remains the same.
