Read the following text and answer any four questions on the basis of the same :
Ecological Indicators : The presence of dragonflies can reveal changes in the water ecosystems more quickly than studying other animals or plants. In fact, from the nymph to the adult stage, the dragonfly has a significant, positive ecological impact. Dragonfly eggs are laid and hatched in or near water, so their lives show an impact on both water and land ecosystems. Once hatched, dragonfly nymphs can breathe in the air or underwater which enables them to eat mosquito larvae, other aquatic insects and worms, and even small aquatic vertebrates like tadpoles and small fish. Adult dragonflies capture and eat adult mosquitoes.
Community wide mosquito control programs that spray insecticides to kill adult mosquitoes also kill dragonflies.
Directions : In the following questions a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as :
Assertion : Releasing dragonflies in areas where there is an outbreak of malarial diseases can be an environment friendly method of control.
Reason : Dragonflies are dominant species and will not allow mosquitoes to reproduce.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'C'. Can you explain this answer?

Understanding the Assertion and Reason
The assertion (A) states that releasing dragonflies in areas with malarial outbreaks can be an environmentally friendly method of control. The reason (R) given is that dragonflies are dominant species and will not allow mosquitoes to reproduce.

Evaluation of the Assertion (A)
- **True Statement**: Releasing dragonflies can indeed help control mosquito populations. Dragonflies and their nymphs are natural predators of mosquitoes, which makes this approach effective.

Evaluation of the Reason (R)
- **False Statement**: While dragonflies do consume mosquitoes, they are not a dominant species in the sense that they can prevent mosquitoes from reproducing. Mosquito populations are influenced by various factors, including environmental conditions and the presence of breeding sites.

Conclusion
- The assertion (A) is true because dragonflies can help control mosquito populations and thus can be a sustainable method for managing malarial outbreaks.
- The reason (R) is false as it inaccurately describes the ecological role of dragonflies in mosquito reproduction.
Thus, the correct answer is option 'C': Assertion (A) is true but reason (R) is false. This conclusion highlights the potential of dragonflies in biological control while clarifying misconceptions about their ecological dominance.
