Concept:‘′‘It's
‘′‘ is a contraction for
‘′‘it is
‘′‘, while
‘′‘its
‘′‘ (without apostrophe) shows possession.
Explanation:‘′‘It's
‘′‘ should be used only where the full form
‘′‘it is
‘′‘ would fit.
In option C,
‘′‘It's imperative
‘′‘ means
‘′‘It is imperative
′, which is grammatically correct.
In options A, B, and D, the word needed is the possessive
‘′‘its
‘′‘ (e.g.,
‘′‘its nature
‘′‘,
‘′‘its performance
‘′‘,
‘′‘its value
‘′‘).
Using
‘′‘it's
‘′‘ there would be incorrect because
‘′‘it is nature
‘′‘ or
‘′‘it is performance
‘′‘ does not make sense.
Thus, only option C uses the contraction correctly.
Answer:Option C:
‘′‘It's imperative that you study hard for success.
‘′‘
