Question

for H atom , degenerate orbitals are​

Answer 1

Answer:

In hydrogen, all orbitals with the same principal quantum number 'n' (1,2,3...) are degenerate, regardless of the orbital angular momentum quantum number'l' (0,1...n-1 or s,p,d..). However, in atoms with more than one electron, orbitals with different values of l for a given value for n are not degenerate.

So the answer to this question is (b) 3s and 3d.
