'even most ' and 'likely most' are wrong way of expressing an idea

the only sentence which corrects this is D

don't know to explain in a gramatical way
but if you read, you can easily tell 'if not most' is the correct way of expressing

I thought "D" changes the meaning somehow.
Has anybody got a grammatical reason to tell that "A" is wrong

D:
>many people, if not most, would agree..... that's the correct construction.

> likely most is wrong...A/B ruled out
> you need do so.. to emphasise ..that she decided to "speak"..so C gone

> Even most ..incorrect...E out

So D left.

Even I think that D changes the meaning of the sentence!

Although Ms. Bakara had previously emphasized that she could not speak for other Black people, she ventured to do so on this one occasion because she firmly believed that many minority people, likely most, would agree with her.

(A) do so on this one occasion because she firmly believed that many minority people, likely most, would agree
(B) speak on this one occasion since she firmly believed that many minority people, likely most, would have agreed
(C) so speak on this one occasion due to her firmly believing that many minority people, even most, would likely agree
(D) do so on this one occasion because she firmly believed that many minority people, if not most, would agree
(E) do so on this one occasion since she firmly believed many minority people, and even most, would likely agree

OA D

I approached this problem with the understanding that "if" is used for a hypothetical scenario. Since Ms. Bakara is not certain, that most Black people would agree with her, we must use "if." Aside from sounding awkward, the four other choices implies that it is certain that most Black people would agree with her and we do not know this.

I think the usages - likely most would...would likely etc are wrong usage...so D is the best !!
