Answer: (B) A-Nonconfirmity, B-Disconfirmity, C-Paraconfirmity Contact A is separating younger sedimentary rocks with older igneous rock (granite) and hence representing a nonconformity. Contact B is the unconformity between two sedimentary successions, so it is representing a disconfirmity. Contact C is the boundary between two sedimentary successions without any erosional evidence and hence indicating a paraconfirmity.

A:- Non conformity /heterolithic unconformity As igneous/granite is below and sedimentary rock on top. Different origin of rocks B:-Disconformity Disconformities are marked by features of subaerial erosion. This type of erosion can leave channels and paleosols in the rock record. C:-. Paraconformity paraconformity is a type of unconformity (gap in the geologic system) in which there is no evidence of a gap in time, because the planes above and below the gap are parallel and there is no evidence of erosion.
