Answer 1

Whose)))))))))))))))))))))))

Answer 2

Whose — правильный ответ.
Whose — это "чей" (чья, чьё, чьи).

Перевод: Чьи это мандарины?

How much, how many — сколько
How often — Как часто

Answer 3

The correct answer is (А) Whose.

The question is asking about the identity of the tangerines, so "whose" is the appropriate pronoun to use to inquire about ownership or possession.
