Which term describes a device that performs a specific function in machinery or electronics?

• A. Pesticide
• B. Absorb
• C. Fertiliser
• D. Device

Answer: (D)

The main idea here is naming something that carries out a specific function within a system, especially in machinery or electronics. A device is exactly that: a piece of equipment designed to perform a particular task or function inside a broader system. In engineering and tech, every component has a job—sensors detect, actuators move, switches control, and so on—and all those items are collectively described as devices. The other terms don’t fit as a general label for a machine or electronic component. A pesticide is a chemical used to kill pests, not a component in a device. Fertiliser is a substance that provides nutrients to plants, again not a part of machinery or electronics. Absorb is a verb describing the action of taking in, not a noun for a component. So, the term that best matches “a thing that performs a function in machinery or electronics” is device.
