Based on the description of the plate boundary where one plate dives underneath another, the following statements are TRUE:

  1. Convection currents within the mantle are moving the plates.
  2. Subduction is occurring at this plate boundary.
  3. This type of boundary can form an oceanic trench.

The first two statements you listed (about rift valleys and it being a divergent boundary) are NOT true in this context. Instead, the scenario described indicates a convergent boundary, specifically one where subduction is occurring.
