I'm going with B. The system-cpu-policer has to be hardware-based, right?

D seems like the false statement to me. CPM-filter entries can't use both a distributed-policer and a system-cpu-policer.

I think D could be the false statement because I remember something about distributed and system policers being separate in some contexts.

I’m a bit confused about the hierarchical policing part. I thought that was a feature, but now I’m not so sure if it applies to control plane traffic.

I feel like I've seen a similar question before, and I think the system-cpu-policer does aggregate traffic, so maybe that's true?

I remember studying about CPM-filter policers, but I'm not entirely sure which statement is false. I think it might be related to the hardware-based aspect.

Wait, what's the difference between hierarchical policing and the system-cpu-policer? I'm a bit confused on that part.

I think option B is false. Hardware-based sounds too strong.
