Assertion (A): An object can have constant speed but variable velocity.
Reason (R): Speed is a scalar but velocity is a vectorquantity.
(1) Assertion (A) is true, Reason (R) is true; Reason (R) is a correct explanation for Assertion (A).
(2) Assertion (A) is true, Reason (R) is true; Reason (R) is not a correct explanation for Assertion (A).
(3) Assertion (A) is true, Reason (R) is false.
(4) Assertion (A) is false, Reason ( \( \mathrm{R}) \) is true.
