Okay, let me think this through step-by-step. The AS_PATH attribute contains the autonomous system numbers the route has traversed, right? And it's used for loop detection and path selection. I'm pretty sure it's a well-known mandatory attribute, so I'll go with D.
Hmm, I'm a bit unsure about this one. I know the AS_PATH is important for BGP, but I can't quite recall if it's mandatory or discretionary. I'll have to think this through carefully.
Hmm, I was a little shaky on the difference between optional and well-known attributes. But D sounds right to me - can't route without that AS_PATH, can we?
