In a system using CSMA/CA, when a collision is detected the node does which of the following?
-- part contents for background part 23
----- text -----
a. Passes the token and must wait for the token to be passed
back before it can retransmit.
-- part contents for background part 24
----- text -----
b. Immediately retransmits the data.
-- part contents for background part 25
----- text -----
c. Waits a random amount of time before checking to see if the
carrier is free.

----- text -----
d. Always repeats data packets so that collisions are not
important.

----- text -----
No. CSMA/CA does not use tokens.
-- part contents for background part 42
----- text -----
No. The node should not retransmit without first checking to see if the carrier is free.
