GMAT Sentence Correction (SC) | Re: One complaint about recently developed “care” robots – robot

Can any instructor/member explain how the meaning is incorrectly conveyed in option A (original sentence). I understand that the complaints w.r.t robots are two
- they do not have the capacity to listen or express emotion
and
- tricking the patients to think that these robots can listen or express is unethical
It'd be great if someone can talk about how this meaning is lost in option A and B.
