### Solution:

The maximum electrons can be described by the quantum numbers $n=5,l=2$ in a particular atom is 10 .

Here,

$n\mathit{=}5$

$l=2$

$m=\left(2×2\right)+1$

$\left(2l+1\right)=5$

maximum

$l=2$ means d-subshell which can accommodate maximum 10 electrons.

Hence, the option C is correct.
