Select the most appropriate option to fill in the blank.
I know that ______ would clear the entrance test if ______ tries hard enough.

Correct option is C

The correct option to fill in the blank is (c) she ; she.
Explanation: Both blanks require a subject (nominative) case pronoun because each functions as the subject of a finite verb— would clear and tries. Therefore, we need she in both places, not her (objective case) or him (objective). (Pronoun in subject position = I, you, he, she, it, we, they / हिंदी: कर्ता रूप सर्वनाम का प्रयोग करें।)
Example: I believe that she will win if she practices daily.
Why other options are incorrect:
· (a) he ; him — second pronoun is objective; should be subject ( he).
· (b) him ; he — first pronoun is objective; should be subject ( he).
· (d) her ; she — first pronoun is objective; should be subject ( she).
Information booster:
· After that when a full clause follows, use subjective case before a finite verb: that they are right; that he knows.
· Objective case is used as object of a verb/preposition: I saw her , for him .
