Correct option is B
The grammatically correct sentence is (B).
Analysis of Each Sentence
- Sentence (A) is incorrect:
- The Error: "...advertisement was exceeding monotonous..."
- The Correction: "Monotonous" is an adjective, so it must be modified by an adverb. The correct form is "exceedingly."
- Sentence (B) is CORRECT:
- The subject "Companies" (plural) matches the verb "stick" (plural).
- The relative pronoun "who" correctly refers to "competitors."
- The sentence is logically and grammatically sound.
- Sentence (C) is incorrect:
- The Error: "Despite of the heavy rain..."
- The Correction: The word "Despite" is never followed by "of." You should use either "Despite the heavy rain" or "In spite of the heavy rain."
- Sentence (D) is incorrect:
- The Error: "The group of activists have launched..."
- The Correction: The subject of the sentence is "The group," which is a collective noun acting as a single unit here. Therefore, it requires a singular verb: "has launched."
Grammar Tip: Collective Nouns
A collective noun (like group, committee, team, or family) is usually treated as singular when the members act together as one unit.
