Explanation

Receive allocates a receiving buffer for the specified TCP connection, telling the TCP layer where to place incoming data and how much space is available - this is a fundamental operation in TCP's flow control mechanism.

Send (A) transmits data over an established connection but does not allocate a receive buffer. Close (B) initiates a graceful four-way handshake to terminate a connection, not buffer management. Abort (C) forcefully tears down a connection by sending a RST segment, discarding any buffered data rather than allocating it.

Memory tip: Think "R for Reserve" - Receive Reserves space in a buffer so incoming data has somewhere to land.
