Take this as you will, but this is how I see it. The correct answer is "Modify the source through the 'ip flow-export source loopback 1' command", as indicated for the reasons below.
A. Wrong, Loopback 2 already has an address as shown in the output, 172.16.1.1
B. Wrong, Does not need to be public address unless leaving your AS.
C. Correct, Loopback 2 is shutdown as indicated the (Unknown) next to the source ip under “show ip flow export”. Assuming that Loopback 1 is not shutdown and has an IP address then C is the correct answer.
D. Exports happen even without the ip flow egress command on the loopback
