Which type of failure is indicated?

Refer to the exhibits.

Exhibit 1

Exhibit 2

Exhibit 1 shows the topology for the network. The network administrator sees the log entries shown in Exhibit 2.

Which type of failure is indicated?
A . A link between Switch-1 and Switch-2 went down. BFD detected the lost connectivity and behaved as expected.
B . Graceful restart helper was not enabled on Switch-2, so BFD was unable to operate correctly, and the session was taken down.
C . A hardware issue caused a unidirectional link; BFD detected the issue at Layer 2 and prevented a broadcast storm.
D . BFD was set up incorrectly on Switch-2, so it caused Switch-2 to lose adjacency with Switch-1 rather than repair the session.
