To match the biosphere reserves correctly, we recall the specific ecological zones in which each reserve is located.
(P) Agasthyamalai Biosphere Reserve → (2)
Located in the southern Western Ghats, the Agasthyamalai region spreads across Kerala and Tamil Nadu. It is a biodiversity hotspot rich in endemic flora and fauna. Hence it matches with statement (2).
(Q) Nokrek Biosphere Reserve → (3)
Nokrek, in Meghalaya, is situated in the Tura Range of the Garo Hills. This region is known for its unique forest ecosystem and the home of the red panda in India. Therefore, it matches (3).
(R) Cold Desert Biosphere Reserve → (1)
The Cold Desert Reserve is located in the Western Himalayan region, especially in Himachal Pradesh (Spiti Valley). Its high-altitude cold desert environment corresponds to statement (1).
(S) Simlipal Biosphere Reserve → (5)
Simlipal is situated in the Mayurbhanj district of Odisha, known for its forests, waterfalls, and tiger reserve. Hence, it matches (5).
Thus, the correct sequence is:
\[
P \to 2, Q \to 3, R \to 1, S \to 5
\]
which corresponds to Option (B).
