In a mobile phone, which of the following wireless technologies is MOST likely to provide Internet connectivity?

RF (Radio Frequency) is the overarching term for the electromagnetic waves used by mobile phones for both cellular data (e.g., 4G, 5G) and Wi-Fi connections, which are the main methods mobile phones use to access the internet.

IR (Infrared) is a wireless technology primarily used for short-range, line-of-sight communication (e.g., remote controls) and is not used for Internet connectivity in mobile phones.

VPN (Virtual Private Network) is a secure tunnel over an existing network connection, not a wireless technology that provides the underlying Internet connectivity itself.

NFC (Near Field Communication) is a very short-range wireless technology used for tasks like contactless payments or device pairing, not for general Internet access.
