Explanation

For any orbital, angular (planar) nodes equal the azimuthal quantum number l, and radial (spherical) nodes equal n − l − 1. A 4d orbital has n = 4 and l = 2, giving 2 angular nodes and 4 − 2 − 1 = 1 radial node. The total of 3 nodes equals n − 1, a useful cross-check. The other options swap or miscompute these values. Hence the answer is 2 and 1.
