A state diagram represents states and transitions, matching (iv). A use case diagram shows interactions between actors and the system, matching (i). A class diagram gives the static structure, matching (ii), and an activity diagram represents workflow, matching (iii). Hence (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii).
