Select the most appropriate option to substitute the highlighted segment in the given sentence.
The migrant said that he did not planning to come back to the city for quite some time.

Correct option is D

The correct substitution of the highlighted words is (d) did not plan.
Explanation:
The phrase “did not planning” is grammatically incorrect because the auxiliary “did” must be followed by the base form of the verb (V1), not the -ing form.
· Incorrect: did not planning
· Correct: did not plan
Grammatical Rule Used:
In simple past negative sentences, we use:
· did + not + base verb (V1)
· Example: She did not go to school yesterday. (Not "did not going")
Information Booster:
· “Plan” = to intend to do something (योजना बनाना)
· “Planning” = gerund/participle form, not used after "did"
Why Other Options Are Incorrect:
· (a) No substitution – Wrong because "did not planning" is grammatically incorrect.
· (b) was not planned – Passive voice and wrong tense for this context.
· (c) do not planning – Incorrect auxiliary verb ("do" is present tense and doesn't go with "planning").
Corrected Sentence:
The migrant said that he did not plan to come back to the city for quite some time.
This sentence is grammatically correct and follows the rules of tense and verb form.
