Answer: B. s, p, d
Explanation:
Principle Quantum Numbers: This quantum number describes the size of the orbital. It is represented by n. n = 1,2,3,4....
Azimuthal Quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. This quantum number is used to describe shape. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Thus if the value of n =3 , the possible values of l are 0 to (3-1) , i.e. 0, 1 and 2.
where l= 0 represents s subshell, l= 1 represents p subshell and l= 2 represents d subshell.
Thus the correct option is B.
