a) from
b) of
c) before
d) none of the above
Correct Answer: b) of
Question from UPPSC Prelims CSAT 2025
Explanation:
The correct collocation is ‘suspicious of’ when referring to people: ‘He is suspicious of all his neighbours.’ ‘From’ indicates origin and does not collocate with ‘suspicious.’ ‘Before’ relates to time or position and is incorrect here. ‘None of the above’ is therefore wrong. Note: ‘suspicious about’ can be used for situations, but with a person we use ‘of.’
