Select the most appropriate option to substitute the highlighted segment in the given sentence. If there is no need to substitute it, select ‘No substitution required’.
It is a story about Mr. and Mrs. Ansari, who had look to rent an apartment in the city.

Correct option is D

The correct substitution of the highlighted segment is "were looking to" to make the sentence grammatically and contextually correct.
Explanation:
· The phrase "had look to" is incorrect because:
· "Had" requires a past participle verb (e.g., "had looked"), but "look" is in the base form.
· "Look to" is incorrect in this context.
· Correct phrase: "were looking to"
· "Were looking" is in the past continuous tense, which matches the meaning of an ongoing action in the past.
· "Looking to" is a correct phrase meaning "trying to find or arrange something".
Grammatical Rule Used:
· Past continuous tense (was/were + verb+ing) is used for actions that were happening at a specific time in the past.
· "Looking to" means "trying to find or arrange something", which fits the context.
Example:
❌ Incorrect: They had look to buy a new house.
✅ Correct: They were looking to buy a new house.
Meanings of other given options and why they are incorrect:
· (a) "is looking to" – Incorrect because "is" is present tense, but the sentence refers to a past event.
· (b) "No substitution required" – Incorrect because the given phrase is grammatically incorrect.
· (c) "were looking for" – Incorrect because "look for" means to search for something rather than to arrange or rent something.
Thus, option (d) "were looking to" is the correct answer. ✅
