B.  

The network latency between inter-Zone ECS instances is lower.

C.  

Intranet communication is available between different Zones in the same region, and data center-level fault isolation can be achieved between Zones.

D.  

Whether you place ECS instances in the same Zone depends on the requirements for disaster recovery and network latency.
