A PS-Poll (Polling Signal) is a control frame used in IEEE 802.11 based wireless local area networks (WLANs) to enable a wireless client device to request buffered frames from an access point (AP). Therefore, PS-Poll is the best choice for this scenario as it specifically enables a station to inform the AP that it can transmit buffered frames. CTS (Clear to Send) is a different control frame used to regulate transmissions in a wireless network. ACK (Acknowledgment) is used to confirm that a received data frame was received without error. RTS (Request to Send) is used to request permission to transmit data frames.
