The statement that BEST explains why the water from the waterfall plunges to great depths when it encounters the standing water and steep geological underwater features below is:

The water from the waterfall is less dense than the water below.

This is because water of different temperatures and salinities can have different densities, and denser water will sink below less dense water. In the case of the underwater waterfall, the differences in density help explain why the water plunges downwards.

The process that has MOST likely occurred in the area where the Mayan road network is covered by the rainforest is:

succession.

Succession refers to the natural process by which ecosystems change and develop over time, particularly after disturbances. In this case, the covering of the roads by rainforest suggests that a secondary succession is taking place as the forest regrows and reclaims the area that was once altered by human activity.
