D is correct answer because shaft is used for transmit the torque so when it rotates tortional stress is induced.

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.
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.
