Select the most appropriate option that can substitute the highlighted word(s) in the given sentence.
One must not be proud of his achievements.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. of one's achievements.
Error concept: Incorrect preposition and pronoun usage.
What is wrong: The original phrase “of his achievements” is correct. Using “off,” “for,” or “by” would make the sentence ungrammatical. Similarly, “one’s” is the correct indefinite pronoun to use with “one must not.”
Grammatical concept:
-
The preposition “of” correctly links pride with the thing someone is proud of.
-
Using “one’s” ensures agreement with the indefinite pronoun “one.”
Incorrectness of the concept in context: Replacing “of his achievements” with other prepositions or pronouns would break grammatical agreement.
How to correct: Use “of one’s achievements.”
Correct phrase/ correction: of one's achievements
Final sentence: One must not be proud of one's achievements.
Hence, the chosen option is correct.
