What is the total number of orbitals present in the shell with the principal quantum number, n = 3

According to Bohr principle, the relation between principal quantum number (n) and radius of the orbit ( r ) is

The letters n, l and m proposed by Bohr, Sommerfeld and Zeeman respectivelt for quantization of angular momentum in classical physics were later on obtained as the results of solution of Schrodinger wave equation based on quantum mechanics. The term n, l, m are named as principal quantum number, azimuthal quantum number and magnetic number respectively. The fourth quantum number i.e., spin quantum number (s) was given by Uhlenback on the basis of two spins of electrons. The first two quantum number also decides the nodes of an orbital. Which statement about energy level in H-atom is correct ?
