Correct Answer: C

Explanation:

UDP Jitter: Measures round-trip delay, one-way delay,one-way jitter, one-way packet loss, and connectivity testing of networks that carry UDP traffic, such as voice. Note that one-way delay requires time synchronization between source and target routers.
ICMP Path Jitter: Measures hop-by-hop jitter, packet loss, and delay measurement statistics in an IP network.
UDP Echo: Measures round-trip delay of UDP traffic.
ICMP Echo: Measures round-trip delay for the full path.
