option B and C

Explanation:

The correct answer is option B and C

the two observers are moving along the same line at different constant speed w. r. t inertial frame.

There will be argued on the length measured in the direction of motion and will also disagree about the time interval.

Time will be affected by the speed of motion as it's dependent on the speed.

Both of them will measure the same relative speed of each other. So, they won't disagree hence option A is not correct.
