Explanation:

Secondary succession occurs in an area where a previously existing ecosystem was disturbed but soil and some biological remnants remain. Options A, B, and D describe primary succession, which starts on barren, lifeless substrates with no prior ecosystem. A forest destroyed by fire retains soil and residual life, so regrowth here is secondary succession.

Answer:

C) Plants growing in a forest that was destroyed by fire
