Explanation:

In ecological succession, primary succession occurs in an area with no soil (like bare rock), and pioneer species (e.g., lichens) are the first to colonize. Secondary succession happens in areas with existing soil (after disturbances like fire), and pioneer species aren't the focus here. Tertiary and quaternary successions are not standard terms for ecological succession. So the correct answer is related to primary succession.

Answer:

A. Primary
