Query related to DS 160 for B2 visa - Family Section

Hi Team ,
I am on H4 visa and planning to invite my mother on B2 visa .
I have one query while filling the DS 160 form section Family As My father is no more(death)
So still I have to mention the Spouse information i.e my Father’s information while filling up the DS 160 for my Mother.

Thanks
Kalyani

Yes, you need to still mention it as it would be on the passport and some of the old documents would have that information.
