Hello Mansha1412,

We hope this finds you well.

To answer your query, even if the pronoun error in Option C were resolved, it would still suffer from multiple flaws.

Option C incorrectly uses the simple present tense verb “find” to refer to an action that concluded in the past but continues to affect the present; please remember, the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present, and the simple present tense is used to indicate actions taking place in the current time frame, indicate habitual actions, state universal truths, and convey information that is permanent in nature. Further, Option C uses the present participle (“verb+ing” – “counting” in this sentence) to refer to the intent behind the action “tried”; please remember, the infinitive verb form (“to + base form of verb”) is preferred over the present participle (“verb+ing” – “counting” in this sentence) for referring to the purpose/intent of an action.
