Question

Regarding assertion and reason, select the right option
Assertion [A]: Flocs present in the effluent help in digestion of nutrients.
Reason [R]: Flocs are lumps of microorganisms that are allowed to grow in the effluent for digestion of the organic nutrients.

• A. Both A and R are correct and R explains A
• B. Both A and R are correct and R does not explain A
• C. Both A and R are incorrect
• D. A is correct and R is incorrect

Answer 1

The correct option is A Both A and R are correct and R explains A

Since the effluent from the primary treatment posseses a large amount of organic nutrients, microbes are required to remove and digest these organic molecules. Hence, microbes are allowed to grow in it. These microbes keep growing and form masses of meshlike structures by associating with fungi called flocs. Flocs help in the digestion of the nutrients in the effluent. Therefore both the assertion and reason are true and the reason is the correct explanation for the assertion.
