I vaguely remember that E could be true since it mentions the internal forwarding class, but I’m not confident about how it applies to VPRN instances.

I practiced a question similar to this, and I think D is definitely related to marking Layer 2 traffic, but I’m uncertain about the specifics of dot1Q.

I think A sounds familiar, but I can't recall if it's specifically about Layer 2 traffic. I need to double-check my notes on QoS.

I remember something about DSCP bits being application-specific, so B might be true, but I'm not sure about A.
