C Correct answer
Explanation

Secondary succession occurs when an existing ecosystem is disturbed but the soil remains intact. After a forest fire, herbs and grasses are typically the first to recolonize the area because they grow quickly from seeds or roots that survived in the soil. Primary succession would occur on bare rock with no soil, while a climax stage represents the final stable community.
