Correct Option - 1
Detailed Solution:Quantum Numbers and Orbitals:
o Total Node = n - 1 (l => Azimuthal Q.N)
o Radial Node = n - l - 1
o Angular Node: l
o If Angular node = 0, then l = 0, i.e., S orbital.
o If Radial nodes = 2, then n - l - 1 = 2.
o Substituting l = 0 gives n - 0 - 1 = 2, so n = 3.
o Therefore, the orbital is 3s.
