Which of the following fish are bred exclusively in the cold regions of India ? I. Catla. II. Tinca. III. Bhekti. IV. Trout. Choose the correct answer from the codes given below.

Result
Your answer: —  Â·  Correct: C
Explanation

Tinca (tench) and Trout are cold-water species bred exclusively in cooler regions of India; reference sources list Tinca and Trout together as species reared in cold regions, making them the exclusive cold-water candidates in the given list . National fisheries classification identifies Trout under coldwater fisheries, further supporting Trout’s exclusive cold-region culture in India [1]. By contrast, Catla is an Indian major carp used in warm‑water freshwater polyculture (not restricted to cold regions) [3]. The other listed fish, Bhekti (identified in sources with warm/coastal affinities), is likewise not an exclusively cold‑region species . Therefore the correct pair bred exclusively in cold regions is II and IV (Tinca and Trout).
