Most probable answer has to be (B) . Deep focus earthquake are found to be associated to the depth of 70 km atleast. It is associated to the foreland basin because of the fact that foreland basin is a structural basin related to subduction settings( normally of two types - Retroarc and Peripheral) . Your wadatti benioff zone is associated to this deep earthquake only.
