The correct answer is :
B) realtime system
Explanation :
In a real time system the CPU is idle most of the time > Real time operating system processing is the process that is defined as a data processing system. In this the time interval required to modify and respond to the input is very small. Real time system is used when it requires hard time for the operation of the processor. In a non multi tasking operating system the CPU becomes idle most of the time, when in a multi tasking program like leaving one job to another, the CPU comes to the idle state, when it comes to the same job again, the CPU comes to the active state .
