The correct answer is: C. Control on Light, Fan etc.
A jumper is a remote control that can be used to control multiple devices, such as lights, fans, and other appliances. It is a small, handheld device that has a number of buttons that correspond to different devices. To use a jumper, simply press the button that corresponds to the device you want to control. The jumper will then send a signal to the device, causing it to turn on, off, or change its settings.
Jumpers are a convenient way to control multiple devices from a single location. They are also useful for people who have difficulty reaching or operating traditional light switches and remote controls.
Here is a brief explanation of each option:
- Option A: Light. A jumper can be used to control lights. To do this, simply press the button on the jumper that corresponds to the light you want to control. The jumper will then send a signal to the light, causing it to turn on, off, or change its settings.

- Option C: Control on Light, Fan etc. A jumper can be used to control a variety of devices, including lights, fans, and other appliances. To do this, simply press the button on the jumper that corresponds to the device you want to control. The jumper will then send a signal to the device, causing it to turn on, off, or change its settings.
- Option D: None of these. This option is incorrect because a jumper can be used to control multiple devices, including lights, fans, and other appliances.
