Zina is using hand gestures which may indicate deafness or loss of hearing, Adora is using a TTY which is a device that is used to communicate through texting/typing so all of them may have hearing loss, are deaf, are hard of hearing, or have possible communication dissabilities.
I believe it could be C. Adora and Riley are partially deaf, Zina may have had a stroke, and Amal is partially blind.
but A. also looks like it could work, i just personally think she doesn't have to be completely deaf to use a TTY, she could just have slight imparements
