Detailed Solution

Atomic orbitals are possible, except is 3f.

Since the first shell may only contain a maximum of two electrons, only the 1s orbital exists in this shell. This means that there is no 1p orbital. With a maximum of 8 electrons, the second shell can contain both 2s and 2 orbitals. Because of this, there are no 3f orbitals.

Hence, option C is correct.
