I think B is the right answer. The CE forwards traffic to all attached PEs but receives from a single PE in the single-active mode.

But in the all-active mode, all PEs can forward traffic, not just one.

Option C seems correct to me. In the all-active mode, all PEs attached to a CE can forward traffic in both directions.
