Question: In an off-network Mission Critical Video (MCVideo) emergency group communication, what triggers an MCVideo client to enter the MCVideo emergency state?
Option 1: Receiving an MCVideo emergency group communication announcement from another participant.
Option 2: Initiating an MCVideo emergency communication or sending an emergency alert.
Option 3: Being provisioned with an MCVideo group designated as the MCVideo emergency group.
Option 4: Upgrading an ongoing group communication to an emergency group communication by another user.
Explanation: According to specifications for off-network emergency group communication in the context of MCVideo, an MCVideo client enters the MCVideo emergency state when it initiates emergency communications or sends alerts, reflecting a proactive declaration of an emergency situation by the client itself, unlike merely receiving announcements, being pre-configured, or relying on others' actions to upgrade the communication state.
