Question What would be the number of electrons in a spectroscopic notation?

I found this a bit "trivial" question regarding quantum numbers but I'm still confused over the given alternatives in the answer. Could it be that whoever posed the question made a mistake or made the question in a silly way?

The problem is as follows:
How many electrons are in the following spectroscopic notation $4d^{9}$?
$\begin{array}{ll}
1.&4e^{-}\\
2.&e^{-}\\
3.&13e^{-}\\
4.&5e^{-}\\
5.&8e^{-}\\
\end{array}$

If I am not mistaken I believe that the answer would be just $9$ as it is strictly stated over the notation for the d-subshell. But this doesn't appear within the alternatives. Upon inspecting the "answer" it still doesn't make much sense as well since $4d^{9}$ is not stable but instead $4d^{8}$ is but for that to happen this atom from which no further information is given has not lost any electrons, needless to say that I cannot assume anything more from the given information, my only guess it is that it could be referring to silver, but again $4d^{9}$ is not the correct configuration for that atom.

What would be the answer or is it just that the question was incorrectly stated or the alternatives aren't right?
