No need to look for other options. A is 100% correct, and the question did not ask to choose more than 1 answer. So you can save time.

Selected Answer: A
It can be it's not C(which looks also correct for first view) because as far as i know there is no CDP option on Cisco firewalls. I have Cisco ASA 5505 and there is no CDP and i found information there is no CDP on Cisco firewalls for security reasons. That's why it could exclude option nr C in my opinion.

Why not C and D? It can collect information from switch and routers and also it is a layer 2 protocol.

Not C Because the option doesn't specifically say from Cisco router, switches, etc. Not D because it does operate on the data-link layer but Not on the physical layer.

It's definitely a good trick question to trip most people up. However, option A is the first thing we learn about CDP, that it's Cisco proprietary.

Remember to choose the most correct answer. C could be correct if they were all Cisco products or capable of running CDP, although that's often not the case. D isn't correct because CDP does not operate on the physical layer.
