Question

sites of earthquakes, volcanos, and trenches are probably *
○ slab pulls
○ active margins
○ abyssal plains
○ passive margins

Explanation:

Active margins are the boundaries between tectonic plates where there is a lot of geological activity. Earthquakes, volcanoes, and trenches are common features at these margins due to the interaction (such as sub - duction) of plates. Slab pulls are a force related to subduction but not the location itself. Abyssal plains are flat areas of the ocean floor with little geological activity. Passive margins are not sites of intense geological activity like earthquakes and volcanoes.

Answer:

B. active margins
