Whom is an object (similar to him, her, them)
Who is a subject (similar to I, he, she, we, they)

I always test another object to make sure whom is the best fit.

One of "them" is blind. I would never say "Presenters at the seminar, one of they is blind..." so I know that it needs to be the object form, or whom.

The word "presenters" is the subject of the sentence.

You can't write "Presenters at the seminar, one who is blind," because the comma-enclosed phrase is a modifier. Who is for subjects.

You could say "The one who is blind will demonstrate...." because now the person who is blind becomes the subject, instead of the group of presenters.

a. one who
b. one of them who
c. and one of them who
d. one of whom
e. one of which

I know the answer for this is D. Also I agree with OG that 'whom' is correct here rather than 'who'. But technically I don't understand how?

If presenters are objective form then what is subject in this sentence?

Also, what is the need of adding 'one who is blind'?

If I write sentence like 'Presenters at the seminar, one who is blind, will demonstrate adaptive equipment that allows visually impaired people to use computers.' will 'presenters' are subject?

I am so confused about this sentence.

A super simple explaination for why its "whom" instead of "who" is that there is a preposition "of" and you surely know that after preposition ( of, at,on )+an objective or Ving
hope that help
