It can with the personal pronoun "elle": "elle est française".

It cannot if you have used "il" or "c'" to translate "it", since both are masculine.

thanks for the advice or as i say in french "Merci pour le conseil'

"it" can translate to "il", "elle" if the thing has been identified, or "c'" if it is a situation or concept.
