Which answer choice correctly distinguishes among the three pieces of data?

piece of data 1 has no footer, but it does have an ip address.
piece of data 2 has no headers.
piece of data 3 has a footer.
a. 1 is a packet, 2 is data, 3 is a frame.
b. 1 is a segment, 2 is a bit, 3 is a packet.
c. 1 is data, 2 is a bit, 3 is data.
d. 1 is a frame, 2 is a bit, 3 is a switch.

pls answer this is part of my test.

a. 1 is a packet, 2 is data, 3 is a frame.

Explanation:

And what is not  mentioned is segment which used TCP/UDP and is part of Transport layer. The packet carries the destination and sender IP address, and is part of the Network Layer. The frame has the Mac address of destination device and senders device and is part of data link layer.

Hence segment has no IP address, hence b. is not correct. Also, data cannot have the IP Address, and Frame has the MAC address, Hence, the above answer. And this arrangement is part of Data Encapsulation.

Also keep in mind data can be anything like a series of bits, or any and it can or not have a header.
