The best choice to include in the plan for restoring the stability and biodiversity of the rainforest while maintaining the town's logging operation is:
A. replanting trees in areas where logging has taken place.
Replanting trees helps to restore the habitat, provides food and shelter for the local wildlife, and supports the overall ecosystem's recovery, thus promoting biodiversity. The other options (B, C, and D) could lead to further degradation of the ecosystem, either by overgrazing, converting habitats to non-forest uses, or introducing invasive species that could disrupt the existing biodiversity.
