Final answer:
C) Standby mode, which is a low-power state that saves the system's state in RAM, allowing for quick resumption of activities.
Step-by-step explanation:
The correct answer is option C) Standby mode. When a computer enters Standby mode, it reduces power consumption by turning off power-hungry components like the monitor and hard drive while preserving the current state of the system in RAM.
The system remains on but in a low-power state, making it quick to resume full operations. This mode is ideal for short breaks, as it allows you to save on electricity and quickly access your work upon return.
