Widow Mother- Not Working

Hi There,

I am applying for my mother's visitor visa. She is a widow and has never worked. She has bank balance and all that to support her.
I am just confused about her "Current Working Status" in the online application.

Should i select 'Unemployed' or 'Supported by Spouse/Partner/Other'.

I obviously don't want to give any false information, and hence very cautious while filling the form. Could some one please guide me

Thanks
