B. Algae are an r-selected species because they have a very rapid growth phase.

Reasoning: r-selected species are those that emphasize high growth rates.

The correct answer is option B, that is, algae are an r-selected species because they have a very rapid growth phase.

The species that show high growth rates, usually exploit less-crowded ecological niches and generate many offspring, each of which exhibiting a comparatively low possibility of surviving to adulthood are known as r-selected species.  

One of the illustrating features of r-selected species is the production of numerous small offspring succeeded by exponential population growth. They mature quickly and require short gestation periods, and exhibits short life spans.
