C. BAT can detect sound at a frequency of 67,000 Hz. Its frequency range is 2,000 - 110,000 Hz67 - 45,000 Hz.
An elephant's frequency range is 16-12,000 Hz.
A tree frog's frequency range is 50 - 4,000 Hz
A dog's frequency range is 67 - 45,000.
Bats have very sensitive hearing to cope with their nocturnal activities. Since the feed at night time, they have difficulty in seeing their prey.
Bats navigate and locate their prey using echolocation. Echolocation is a method where bats produce a very loud sound and assess the sound's echo. The echo has two types of frequency. Constant frequency, used to detect object, and Frequency modulated, used to assess the distance of the object. Bats then know the presence of its prey as well as its location.

Explanation:
Answer:
b) Bioremediation
Explanation:
The use of natural occuring or intentionally introduced micoorganisms to treat environmental pollutants is called as Bioremediation.
- Most of the bioremediation processes includes oxidation-reduction reaction.
- The natural degradation process of pollutants is improved by bioremediation.
- Green plant, Decomposers and their enzymes are used in bioremediation to imrprove the condition of the environment.
