Choose the grammatically correct sentence:

The correct answer is Option (1) → Neha’s younger brother accompanied her to the dentist on Monday.

Verbs that take their object directly:

• The object is the person or thing the action is done to. Some verbs are followed by their object directly, with no preposition in between.
• “Accompany” is one of them. In “accompanied her”, the object “her” comes straight after the verb.

Why the Other Options are Incorrect?

Option 2: At the dhaba, the truck drivers ordered for hot parathas and tea. — Incorrect. The given sentence says “ordered for hot parathas”. The verb “order” takes the thing ordered as its object directly, without “for”.
Corrected: At the dhaba, the truck drivers ordered hot parathas and tea.

Option 3: Two stray dogs attacked on the postman near our gate yesterday. — Incorrect. The given sentence says “attacked on the postman”. The verb “attack” takes its object directly, without “on”.
Corrected: Two stray dogs attacked the postman near our gate yesterday.

Option 4: The students of Class 12 requested for an extra Physics class before the exam. — Incorrect. The given sentence says “requested for an extra Physics class”. The verb “request” takes its object directly, without “for”.
