A) Study A does a better job of meeting criteria for establishing causality between variables.
B) Neither A nor B does a better job of meeting the criteria for establishing time order.
C) Study A is preferable to study B in terms of the criterion of association only.
D) Study B does a better job of meeting criteria for establishing causality between variables.
