C Correct answer
Explanation

ATM networks are connection-oriented. Making a call requires first sending a message to set up a connection. After that, subsequent cells follow the same path to the destination. Cell delivery is not guaranteed, but their order is guaranteed. If cells 1 and 2 are sent in that order, then they will arrive in that order, never first 2 and then 1.
