Which routing technique can the network administrator use so that the rest of the network is not affected by the flapping issue?

Refer to the exhibit.

Company XYZ BGP topology is as shown in the diagram. The interface on the LA router connected toward the 10 1.5.0/24 network is faulty and is going up and down, which affects the entire routing domain.

Which routing technique can the network administrator use so that the rest of the network is not affected by the flapping issue?
A . The LA administrator should use route aggregation to summarize the 10 1 4.0/24, 10 1 5 0/24, 10.1.6.0/24, and 10 1 7 0/24 networks toward Chicago
B. The LA administrator should use route dampening for the 10.1.5 0/24 network so that it does not get propagated when it flaps up and down.
C. The LA administrator should use route filtering to block the 10.1.5.0/24 network from getting propagated toward Chicago and New York.
D. The Chicago administrator should use route filtering to block the 10.1.5.0/24 network from coming in from the LA router.
