(c) Transmission delay

(d) Propagation delay

This question was addressed to me in examination.

Question is taken from Delays and Loss topic in division Security & Physical Layer of Computer Network

Answer 1

The correct choice is (a) Processing delay

The best I can explain: Processing delay is induced at a router’s or other network processor’s end in the path of the packet and is caused by the time taken by the processor to examine the packet’s header to decide the further path of the packet.
