B, E are correct. In the 300-420 Cert Guide - Chapter 3 "Routing Protocol Characteristics, EIGRP, and IS-IS" - "IS-IS Interface Types" on page 117 it states: "IS-IS only has two network types (or interface types): point-to-point and broadcast."

Band E are correct: "In Intermediate System-to-Intermediate System (IS-IS) Protocol, there are two types of networks: point-to-point and broadcast. Unlike Open Shortest Path First (OSPF) Protocol, IS-IS does not have other network types like non-broadcast and point-to-multipoint."
