Which connector is likely to be found on the iPhone 5 and later models?

The Lightning connector is the correct answer as it was introduced with the iPhone 5 and has been utilized in all subsequent iPhone models up to the present date. This connector was designed to be compact and reversible, allowing users to plug it in either way, enhancing user convenience. The Lightning connector also supports advanced features such as higher data transfer rates and improved power delivery compared to its predecessors.

Mini USB and Micro USB connectors are older standards, primarily used by devices prior to the widespread adoption of the Lightning connector. They were phased out with the introduction of more modern devices. Thunderbolt, while a high-speed connection standard, is not compatible with the iPhone 5 or its later models, as it is more commonly found in computers and some peripherals. Thus, the Lightning connector is the definitive choice that aligns with Apple's design direction for their devices starting with the iPhone 5.
