Question: In which scenario does the "Call Present" state exist for a mobile terminating call?
Option 1: When the UE has sent a call establishment request and is waiting for a response from the network.
Option 2: When the network has received a satisfactory response to a call establishment request.
Option 3: When the network has sent a call establishment request but has not yet received a satisfactory response.
Option 4: When the UE has rejected a call establishment request.
Explanation: The "Call Present" state is specific to mobile terminating calls, where the network initiates the call setup. This state indicates that the network has taken the first step by sending a call establishment request but is still waiting for a response from the UE, which could be an acceptance or rejection of the call.
