  3. CNilgiri
  4. DPanchmarhi

Explanation

The correct answer is B because Nallamalai is a range of hills located in the Eastern Ghats of Andhra Pradesh and Telangana, but it has not been designated as a Biosphere Reserve by the Government of India. In contrast, Agasthyamalai, Nilgiri, and Panchmarhi are all officially recognized Biosphere Reserves. Specifically, Nilgiri was the first one established in India, while Agasthyamalai and Panchmarhi are also part of the UNESCO World Network of Biosphere Reserves.
