Answer is option B.
The strain energy stored in a solid circular shaft in torsion, subjected to shear stress (τ) , is:τ2/ 4G * Volume of the shaft.

D is not a correct answer, Option B is the correct answer.
U = 1/2(T.θ)
U = 1/2(T^2L/GJ)
U = (τ^2/2G)Volume of shaft.
U = 1/2(T.θ)
U = 1/2(T^2L/GJ)
U = (τ^2/2G)Volume of shaft.

OPTION B Is true when;
The strain energy stored in a solid circular shaft subjected to shear stress (Ï„) is (where C = Modulus of rigidity for the shaft material).
Option D is true when,
The strain energy stored in a solid circular shaft subjected to torsion (T) is (where C = Modulus of rigidity for the shaft material).
The strain energy stored in a solid circular shaft subjected to shear stress (Ï„) is (where C = Modulus of rigidity for the shaft material).
Option D is true when,
The strain energy stored in a solid circular shaft subjected to torsion (T) is (where C = Modulus of rigidity for the shaft material).
