Which statement describes a feature of the IP protocol?

• IP encapsulation is modified based on network media.
• IP relies on Layer 2 protocols for transmission error control.
• MAC addresses are used during the IP packet encapsulation.
• IP relies on upper layer services to handle situations of missing or out-of-order packets.

Explanation: IP protocol is a connection-less protocol, considered unreliable in terms of end-to-end delivery. It does not provide error control in the cases where receiving packets are out-of-order or in cases of missing packets. It relies on upper layer services, such as TCP, to resolve these issues.
