Suppose there are two links between source and destination, with one router connecting the two links. Each link is 5,000 km long with a transmission rate of 10 Mbps. Assume the propagation speed is meters/sec. There is a 30 Mbit MP3 file that is broken into 3 packets, each of 10Mbits. Ignore headers that may be added to these packets. Also ignore router processing delays. Assuming store and forward packet switching at the router, the total delay is

a. 3.05 seconds

b. 4.05 seconds

c. 6.05 seconds

d. none of the above
