networks (WANs)?

A.
PPP

B.
X.25

C.
Frame relay

D.
SLIP

Explanation:
Frame relay is a telecommunication service designed for cost-efficient data
transmission for intermittent traffic between local area networks
(LANs) and between end-points in a wide area network (WAN). Frame relay puts data in a variablesize unit called a frame. It checks for lesser
errors as compared to other traditional forms of packet switching, which speeds up data
transmission. When an error is detected in a frame, it
is simply dropped. The end points are responsible for detecting and retransmitting dropped frames.
