The correct answer is: Did, study.
Gandhiji studied in Rajkot from 1874 to 1887. He attended the Samaldas Sanskrit School and the Rajkot High School. He was a good student and excelled in his studies. He was also interested in social reform and began to participate in activities to help the poor and oppressed.
The other options are incorrect because they do not accurately reflect Gandhiji’s experience in Rajkot. Option A, “Was, study,” is incorrect because it uses the past tense to describe Gandhiji’s studies. Gandhiji was a student in Rajkot, but he is no longer a student. Option B, “Does, studied,” is incorrect because it uses the present tense to describe Gandhiji’s studies. Gandhiji did study in Rajkot, but he does not study there anymore. Option C, “When, studied,” is incorrect because it uses the interrogative form to ask about Gandhiji’s studies. The question is not asking when Gandhiji studied in Rajkot, but rather what he did in Rajkot.
