SSC CGL 2023 PYQ — Question 45

The correct answer is Option 1 i.e. Rhodophyceae.

Rhodophyceae, commonly known as red algae, are a group of primarily marine algae characterized by their reddish color due to the presence of the pigment phycoerythrin. This pigment masks the green of chlorophyll, giving these algae their distinctive hue. Red algae are important in marine ecosystems, contributing to coral reef formation and serving as a food source for various marine organisms. They are also used in human industries, such as the production of agar and carrageenan, which are used as food additives and in other applications.
