which type of basin forms at transform boundaries?\nrift\nwedge\narc\nstrike - slip

Brief Explanations:

Transform boundaries involve horizontal - sliding motion between tectonic plates. Strike - slip basins form at these boundaries due to the lateral movement and associated stress. Rift basins form at divergent boundaries, wedge basins are not specifically associated with transform boundaries, and arc basins are related to convergent plate boundaries involving subduction.

Answer:

D. strike - slip
