Which statement defines the control frame operation between two stations?

Wähle eine der folgenden:

A station sends an RTS frame as the first step in a three-way handshake that is required before sending data frames.
A station responds to an RTS frame with an ACK frame, thus providing permission for the requesting station to send a data frame.
If the sending station does not receive an ACK frame within a predetermined period of time, the sending station will drop the connection.
After receiving a data frame, the receiving station will send an ACK frame to the sending station if no errors are found.
