Show the answer and explanation
Correct answer: D
Explanation
Uma is seventh; three candidates between Uma and Zoya put Zoya third, and Tenzin second.
Yash is not at an end and not next to Zoya: fifth or sixth. Varun is two seats to Yash's left; the third seat is taken, so Yash is sixth and Varun fourth.
Ishaan is next to Varun: fifth. Wahida takes the left end.
Row, left to right as they sit: Wahida, Tenzin, Zoya, Varun, Ishaan, Yash, Uma.
Wahida is first and Yash sixth; Tenzin, Zoya, Varun and Ishaan sit between them: 4.
Worth noting
3 leaves one of the four out, usually Tenzin, who sits right next to Wahida.
