Choose the suitable option replace to highlighted sentence- we must prevent him to go there.

Explanation:

The correct structure with the verb “prevent” is:

👉 prevent + object + from + verb(-ing)

So the sentence becomes:
“We must prevent him from going there.”

❌ Why other options are wrong:

1. for going there
   ❌ Incorrect preposition with “prevent”
2. from to go there
   ❌ Wrong structure (cannot use “to + verb” after “from”)
3. not go there
   ❌ Missing “from” and incorrect pattern

 Extra Facts:

1. Similar verb patterns:
   • stop someone from doing something
   • keep someone from doing something
   • discourage someone from doing something
2. Common exam trap:
   ❌ prevent him to go
   ✔ prevent him from going
3. Short trick:
   👉 After from → always use verb + ing

Final Answer:

from going there
