I believe cochlear implants since deaf people often read lips and watch hands which is both sign language and visual communication
i think deaf people would prefer getting together in person as well since it is easier to read lips and/or see signs
whilst cochlear implants not everyone will have them and they wont be bothered by it so thats why i'm saying Cochlear implants
sorry if im wrong...
It’s either b or C! I hope that all helps
