Answer 1

The correct option is B i, ii and iii

As we know that
i. Rest and motion are relative terms, so there is nothing like "Absolute rest" or "Absolute motion"
ii. Frame of reference is always for observer.
iii. Time does not depend on the frame of reference.

Hence, statments i, ii and iii are correct. (Option b)
