Assertion (A): The stretching of a coil is determined by its shear modulus.

Reason (R): Shear modulus change only shape of a body by keeping its dimensions unchanged.
(1) Both Assertion (A) and Reason (R) are True and the Reason (R) is a correct explanation of the Assertion (A).
(2) Both Assertion (A) and Reason (R) are True but Reason (R) is not a correct explanation of the Assertion (A).
(3) Assertion (A) is True but the Reason (R) is False.
(4) Assertion (A) is False but the Reason (R) is True.
