Answer:
b. specialized for absorbing shorter wavelengths of light that penetrate deeper into the water for photosynthesis.
Explanation:
There are two lights which are responsible for the photosynthesis in plants and algae i. e. red and blue light. These two lights are absorbed by the plants and algae in the process of photosynthesis while most of the light colors are reflected. In water red light remains in low depth while blue light penetrate deep into the water due to its shorter wavelength. So that's why red algae can grow due to the presence of blue light and photosynthesis occurs.

B.
