Check true$/$correct assertions$($s$)$ that apply to the Ethernet II and or IEEE $802\mathrm{.}3$ protocol.

A$.$ Ethernet II adopts the CSMA$/$CD MAC protocol that prevents the collisions over the shared access media.

B$.$ IEEE $802\mathrm{.}3$ is an unreable protocolthe destination discards erroneous frames without notifying the sender$.$

C$.$ Ethernet II is connectionless, the source transmits without checking if the destination exits or it is ready to accept a frame.

D$.$ Ethernet II protocol header is varying length, as it stores to the length of the payload.

E$.$ Ethernet II protocol does not implement theflow control as the source does not check if the destination can sustain the traffic.
