Torsion energy = 1/2 * T * angle of twist.
So, option D is correct.
So, option D is correct.

But torsion occurs due to shear force. So o0tion (D) is correct.

Answer D only applicable when the shaft is under torsion. So here it is not perfect and answer B is correct.

Actually Q should be following way.
The strain energy stored in a solid circular shaft subjected to torsional stress (τ) is (where C = Modulus of rigidity for the shaft material),
then opt D.
OR
The strain energy stored in a solid circular shaft subjected to shear stress (τ) is (where C = Modulus of elasticity for the shaft material),
then opt B.
The strain energy stored in a solid circular shaft subjected to torsional stress (τ) is (where C = Modulus of rigidity for the shaft material),
then opt D.
OR
The strain energy stored in a solid circular shaft subjected to shear stress (τ) is (where C = Modulus of elasticity for the shaft material),
then opt B.

Right answer is [B].
[D] is for strain energy stored in a material due to torsional stress. Here, shear stress is given for which B is true.
