The correct answer is: I(3p), II(3d), III(3s)

No of radial node  =  n  - ℓ - 1  .

I(3p) ---- n = 3 and ℓ =1.       One radial node         
  
II(3d) ----  n = 3 and ℓ =2.       No radial node         

III(3s) ----  n = 3 and ℓ =0.        Two radial nodes.    

All the orbitals provided in choices belong to match. I(3p), II(3d), III(3s)
