Show answer and explanation

Correct answer: MTA

Explanation

The official key awards **marks to all**. Established residents exist and all are academicians, so D certainly follows. If “these academicians” refers specifically to established residents, A and C also follow and express the same intersection. The wording therefore does not support a unique MCQ answer; the official MTA grading is retained.
