A network engineer wants to limit the EIGRP query scope to avoid high CPU and memory utilization on low-end routers as well as limiting the possibility of a stuck-in-active routing event between HQ and branch offices. Which action is the best way to achieve these goals?

A.	Configure all routers at HQ and branch offices as EIGRP stub.
B.	Configure all routers at branch offices as EIGRP stub.
C.	Configure all routers at branch offices as EIGRP stub and allow only directly connected networks at branch offices to be advertised to HQ.
D.	Configure different autonomous systems numbers per each branch office and HQ and redistribute routes between autonomous systems.
