The orbital having `m = - 2` should not be present in the following sub-shell

Options

A. d
B. f
C. g
D. p

Explanation

To determine which subshell does not contain an orbital with \( m = -2 \), we need to analyze the possible values of the magnetic quantum number \( m \) for different subshells. The magnetic quantum number \( m \) can take values from \(-l\) to \(+l\), where \(l\) is the azimuthal quantum number corresponding to the subshell.

### Step-by-Step Solution:

1. **Identify the Subshells and their Corresponding \( l \) Values:**
- **s subshell:** \( l = 0 \)
- **p subshell:** \( l = 1 \)
- **d subshell:** \( l = 2 \)
