Select the most appropriate option to fill in the blank.
Researchers ___________ new technologies to improve recycling processes in the near future.

Correct option is C

✔️ The correct answer is (c) are developing.
Correct sentence: Researchers are developing new technologies to improve recycling processes in the near future.
Explanation:
· The present continuous tense ( are developing) is used to describe an action that is currently in progress or expected to happen soon. Since the sentence talks about current efforts or near-future activity, the present continuous is appropriate.
Grammatical rule used:
· Present continuous tense is formed using am/is/are + verb-ing and is used for ongoing actions or planned near-future events.
Explanation of the rule in Hindi:
· जब कोई कार्य अभी हो रहा हो या निकट भविष्य में होने वाला हो, तब “am/is/are + verb-ing” का प्रयोग किया जाता है।
Meanings of other options:
· (a) has been developing – Incorrect subject-verb agreement; “has” is singular, but “researchers” is plural.
Hindi meaning: अनुचित संयोजन ❌
· (b) develop – Simple present; doesn’t indicate ongoing/planned action.
Hindi meaning: सामान्य वर्तमान काल ❌
· (d) was developing – Past continuous tense; doesn’t match the future context.
Hindi meaning: भूतकाल का संकेत ❌
