Sentence Correction (SC) | Re: Weighing in on the controversial subject, the President announced that

When we talk about of making choices then "whether" makes more sense than "if"."If" is generally used for conditional sentences so A is out

C-whether or not is redundant so C is out

D- wrong as we don't have anything possessive here for which "its" is used

E- construction here "likelihood" for it is not good and is also wordy as compared to B

So B is correct choice

Give kudos if ithelps
