Torsion also produces shear stress but for shaft shearing due transverse load is not appropriate (as in the case of beams) that's why option "B" is not true here, it must be shearing by twisting moment of the shaft that's why option "D" is absolutely correct.

Yes,
For shear stress answer should be "B".
For torsion, it's Ï„^2/4C (D^2+d^2/D^2) V.
For shear stress answer should be "B".
For torsion, it's Ï„^2/4C (D^2+d^2/D^2) V.

For shear stress answer should be "B".
For torsion it's τ^2/4C (D^2+d^2/D^2) V.
For torsion it's τ^2/4C (D^2+d^2/D^2) V.

Is should be D^2 in the denominator.
Ashley said:

Using Equation, Strain energy, U = (1/2) TQ.
Obtain expression for T and Q from the torsion equation.
Q is the angle of twist in radians.
