Hi.. You might want to correct/edit this, as in the beginning it says the sentence is correct, while in the end it appears to be calling it incorrect. The intended message about omission of "who" is not clear.
The sentence is correct in its current form. It would be incorrect to remove 'who' from it. That is the reason it mentions "Incorrect". I have added the words "to remove who" to clarify it further.
