Concepts and reason
The concept used to solve this problem is based on quantum numbers.
There are four set of quantum number namely, principal quantum number, n, azimuthal quantum number, l, magnetic quantum number, m and spin quantum number, s. Principal quantum number tells about the subshell in which electron is present. It values varies from 1 to n here, n is natural integer.
Azimuthal quantum number, l tells about the shape of orbital. Its values vary from 0 to image, here, n is principal quantum number.

Fundamentals
For a correct set of quantum number, all 4 quantum numbers must satisfy their possible ranges. For example, azimuthal quantum number, l cannot be more than principal quantum number, n. Also, there are only two possible values of spin quantum number that is image

Answer:

For s orbital, value of azimuthal quantum number is zero. Therefore, magnetic quantum number image has one value that is equal to zero.

Part A
Possible value of image for an electron in s orbital is zero.

Total number of magnetic quantum numbers is calculated as 2l+1. Value of azimuthal quantum number is zero. Therefore, total number of magnetic quantum numbers will be:
image
And it varies from -l to +l therefore, it is single value equals to zero.

Part B
Possible values of image for an electron in d orbital are -2, -1, 0, 1 and 2.
