It's not J/R.
It is tou/R.
It is tou/R.

@Vinod Uv.
Torsional rigidity is the amount of resistance a cross-section has against torsional deformation, it is termed as GIp.

j = Polar moment of inertia.
r = Radius.
r = Radius.

Polar modulus and torsional section modulus are both same. Polar modulus should not be confused with polar moment of inertia.

Since j is polar moment of inertia (pi/32)*d^4 so in that clue we can conclude the solution.
