q6-  Which statement is true about the operations of the IPv4 protocol? Select one: A. IPv4 operates independently of the media that carry the data at lower layers of the protocol stack. B. IPv4 is a connection-oriented protocol that requires some control data to be exchanged to establish the connection before data transmission. C. IPv4 includes additional fields in the IP header, which are required for reliable delivery of the packet. D. IPv4 provides error control and tracking for the data delivery, and retransmits the packet if it is corrupted.
