Select the most appropriate option to fill in the blank.
One is sure ________ what one sees.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. about.
The correct preposition to use with the adjective "sure" when referring to a fact or piece of information is "about."
"Sure about" means confident or certain of something.
Why the other options are incorrect:
With: Used to indicate association or possession is not suitable here.
Around: Refers to physical position or movement is irrelevant in this context.
Without: Implies absence which does not fit the meaning of certainty.
Final Sentence: One is sure about what one sees.
Hence, the chosen option will be correct.
