Which of the following is an example of an open loop system?

A Household Refrigerator
B Respiratory system of an animal
C Stabilization of air pressure entering into the mask
D Execution of program by computer

Correct Answer: Execution of program by computer

Execution of a program by a computer is an example of an open loop system as the feedback mechanism is not taken by the computer program and set programs are used to get the set output.
