Suppose, It is $02$:$00$:$00$ PM in your clock and you start transmitting the frames from station A$.$ The network is using CSMA$/$CD$.$ Given, the $10$ minutes propagation time from the station A to station D including all the necessary delays,

a$)$ What is the time in your clock after completing the transmission of the frames if you want to detect the possible collision in the worst case scenario?

b$)$ What will happen if you have stopped transmitting before the time that you have calculated? Validate your answer with a CSMA$/$CD diagram.
