Sentence Correction (SC) | Re: Presenters at the seminar, one who is blind, will demonstrate adaptive

HiGMATNinja ,
Can you please clear mydoubt.?

If the word is a subject (the "doer" of an action), we use "who." If the word is an object (the recipient of an action) we use"whom."

As per the sentence - 'the presenters' is the subject and 'will demonstrate' is the verb that is the presenters are doer of the action .
However, we are still using whom. Why
...
