What does it mean if you say something has "Bluetooth capabilities"?

Saying that a device has "Bluetooth capabilities" means that it can use radio technology to wirelessly connect and communicate with other devices over short distances. Bluetooth technology allows for the transmission of data and audio between devices without the need for physical cables. This is particularly useful for connecting peripherals like headphones, keyboards, and mice, as well as for enabling data exchange between smartphones, tablets, and computers.

The other options do not accurately reflect what Bluetooth capabilities entail. The notion of connecting only via cables contradicts the essence of Bluetooth, which is designed for wireless communication. Claiming compatibility solely with Apple products is misleading because Bluetooth is a universal standard that works across devices from various manufacturers, not limited to any specific brand. As for the requirement of being within a physical range of just 1 meter, Bluetooth typically operates at greater distances, generally up to 10 meters or more, depending on the Bluetooth version and device specifications, making this too restrictive.
