Detailed Solution

An electron in an orbital of high angular momentum stays away from the nucleus than an electron in the orbital of lower angular momentum.

According to Bohr's theory, angular momentum is an integral multiple of $\frac{h}{2 π}$ .Hence, the ground state angular momentum is h equal to $\frac{h}{2 π}$
Statements b and c are incorrect. As we know the principal quantum number depends on size whereas azimuthal quantum number doesn't depend on size.
