Answer:- b. +3

Explanations:- Charge of a metal ion is equal to the number of valence electrons it has as it loses these electrons to have its nearest noble gas like electron configuration.

Al has 3 valence electrons and being a metal it loses all of these and so the charge of Al ion is +3. It could be shown as:

Al\rightarrow Al^+^3+3e^-

So, the right choice is b. 3+.
