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 a preposition that 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.
