### Solution:

The maximum possible set(s) of quantum no. are possible for  electron of Fe is 6.

The electronic configuration of Fe is

$1{s}^{2}2{s}^{2}2{p}^{6}3{s}^{2}3{p}^{6}3{d}^{6}4{s}^{2}$

For 2p orbital

$n=2,l=1,m=+1,0,-1$

The possible  number of sets are

$\begin{array}{l}⇒n=2,l=1,m=+1,s=±\frac{1}{2}\\ n=2,l=1,m=-1,s=±\frac{1}{2}\\ n=2,l=1,m=0,s=±\frac{1}{2}\end{array}$

From the above observation it is obtained that the maximum possible set(s) of quantum no. are possible for  electron of Fe is 6.
