Explanation:

Permafrost contains organic matter (e.g., dead plants/animals) frozen for long periods. When it melts, microbes break down this organic matter, releasing CO₂. Hydrolysis involves water breaking bonds (not CO₂ release here), and photosynthesis absorbs CO₂, so decomposition is correct.

Answer:

B. decomposition
