Answer 1

The correct option is D

Magnets in junkyards

Magnets have many applications in our daily lives. Large size magnets are used in junkyards for separating magnetic materials that can be recycled or reused. The other three options also use magnets but they are the application of the magnetic properties and not separation like magnetic door latch on a refrigerator so the door is shut properly, a compass to give direction and hard disk to record data.
