Please correct the option 'C'.

Option c. It promotes the growth of algae which in turn gives off oxygen. So it increases DO.

Option C is correct. Sunlight increases the D.O content.

Like plants, algae go through the process of photosynthesis in order to produce complex organic compounds such as proteins, fats and carbohydrates. So, A IS ANSWER.

Impedes means delay or prevent. Algae grow in the dark areas. So algae can't grow in sunlight.

So, option B is correct.

It may be A or C which one we will go for please someone explain it.

Ya answer is C as sunlight helps to grow algae not bacteria in presence of sunlight we should go for C.

Sunlight depletes nutrients from the surface of the water in summer. So the growth of algae reduces so b correct. But the same time due to sunlight due to photosynthesis DO increase. But due to high temperature DO decrease. So option B is correct.
