The following sentence contains four highlighted words. Identify the option that contains an error. "They were sitting on the chairs in the class talking to each other when they entered in a heated argument."

Correct option is C

Explanation of the Correct Answer: · The incorrect phrase is "entered in a heated argument."
· The verb "enter" does not require the preposition "in."
· Correct usage: "entered a heated argument."
· The correct sentence should be:
· "They were sitting on the chairs in the class talking to each other when they entered a heated argument."
Why Are the Other Options Incorrect? · (a) "On" → Correct preposition for "on the chairs."
· (b) "To" → Correct preposition for "talking to each other."
· (d) "When" → Correct conjunction for indicating time.
Thus, the correct answer is (c) "In" (incorrect preposition with "entered").
