A client process P needs to make a TCP connection to a server process S. Consider the following situation: the server process S executes a $\text{socket()}$, a $\text{bind()}$ and a $\text{listen()}$ system call in that order, following which it is preempted. Subsequently, the client process P executes a $\text{socket()}$ system call followed by $\text{connect()}$ system call to connect to the server process S. The server process has not executed any $\text{accept()}$ system call. Which one of the following events could take place?
