Choose the most suitable option to replace the highlighted part of the sentence:
He is looking forward to meet you soon.

Correct option is A

The correct substitution of the highlighted words is (a) to meeting you soon.
Explanation: The expression “look forward to” is a fixed phrase in English where “to” is a preposition, not an infinitive marker. Therefore, it must be followed by a noun or a gerund (V-ing), not the base verb. Hence, “to meet” is incorrect and should be replaced with “to meeting.” This correction keeps the meaning intact and makes the sentence grammatically accurate.
Grammatical rule used:
· look forward to + noun / V-ing (gerund)
· Example: I am looking forward to seeing you again.
· Information booster / exceptions related to the topic:
· Many phrases ending with “to” take V-ing because “to” works as a preposition: be used to doing, be accustomed to doing, be committed to doing, object to doing.
