Text Solution

Verified by Experts
The correct answer is:
C

Red algae contain phycoerythrin, which allows them to absorb blue light that penetrates deepest in water, so they are found at greater depths in oceans. Green algae are mostly freshwater or shallow water organisms. Brown algae are mainly found in colder, deeper coastal waters (not the shallowest). Red algae are not only marine; some can occur in freshwater too.
