Algal blooms impart a distinct color to water due to their pigments. The correct answer is (a).
The algal blooms produce a large number of photosynthetic pigments that facilitate the production of food by means of photosynthesis, they are known as the carbon fixators of the atmosphere, where they fix the carbon dioxide by photosynthesis.
The pigments present in them vary from green, red or brown depending upon its species. Some of the pigments are harmful to other organisms.
