The correct option is
C s-orbital
Explanation:
The s subshell contains a single s orbital, so the magnetic quantum number, which tells you the orientation of the orbital that holds a given electron, can only take 1 possible value.s orbital cannot be described by a magnetic quantum number equal to −1.
For l=0, m value should be 0 indicates s orbital.
For l=1, m value should be −1,0,+1 indicates s,p orbitals.
For l=2, m value should be −2,−1,0,+1,+2 indicates s,p,d orbitals.
For l=3, m value should be −3,−2,−1,0,+1,+2,+3 indicates s,p,d orbitals.
For l value −1 the electron may present in p or d or f orbital it cannot be in s orbital.
Hence the correct answer is option (C)
