Select the most appropriate option to fill in the blank.
His friends disagreed _________ him on that point.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. with.
In the sentence:
His friends disagreed _________ him on that point.
the verb “disagree” when expressing a difference of opinion requires the preposition “with” before a person. The correct phrase is “disagree with someone”.
Thus, the complete sentence should read:
His friends disagreed with him on that point.
Why the other options are incorrect:
Option 2 ('for'): 'Disagreed for him' is not a valid or commonly used construction—doesn't fit logically.
Option 3 ('on'): While “disagree on” can be used with topics or issues, when there's a person involved ('him'), it must be 'disagreed with him on…'—not just 'on' alone.
Option 4 ('to'): 'Disagreed to him' is not a standard English phrase and is grammatically incorrect.
