Answer

Answer:

D. Basic toaster

Explanation:

Step1: Understand open - loop systems

Open - loop systems do not have feedback. They operate based on pre - set inputs without adjusting according to output.

Step2: Analyze traffic light system

Traffic lights follow a pre - set time sequence but can have some adaptive features (semi - open loop in some cases), not a pure open - loop.

Step3: Analyze home heating system

Home heating systems use thermostats for feedback to maintain a set temperature, so they are closed - loop.

Step4: Analyze automatic irrigation system

Some automatic irrigation systems can have soil moisture sensors for feedback, making them closed - loop or semi - closed loop.

Step5: Analyze basic toaster

A basic toaster has a pre - set time or heat setting and does not adjust based on the "doneness" of the toast. It is an open - loop system.
