Assume that a user is connected to a Frame Relay network through a T-3 line where Bc=60 Mb/5s, Be=60 Mb/10s and Access rate = 45 Mbps. If the user sends data at 16 Mbps, is it guaranteed that frames are never discarded? Select one:

a. No, since 16 Mbps > Access rate, frames will be discarded only if there is a congestion

b. No, but since 16 Mbps < Bc + Be, frames will be discarded only if there is a congestion

c. Yes, since 16 Mbps < Access rate

d. Yes, since 16 Mbps > Bc + Be

e. Yes, since 16 Mbps < Bc + Be
