The following sentence has been split into four segments. Identify the segment which contains a grammatical error.
He will be leaving / home at 8 a.m. / to beating / the office rush hour.

Correct option is C

Option (c) contains an error.
Error: "to beating" is incorrect. It should be “to beat” – we use the base form of the verb after “to” when it indicates purpose.
Grammatical rule: When "to" is used as part of an infinitive to express purpose, it's followed by base verb (V1), not a gerund.
Correct sentence: He will be leaving home at 8 a.m. to beat the office rush hour.
Example: She studies hard to pass the exam.
Information Booster: Only when “to” is a preposition (e.g., look forward to), it is followed by a gerund.
