What are two possible ways to achieve this goal (Each correct answer presents a complete solution?

A WCF service code is implemented as follows. (Line numbers are included for reference

A.
Change the service behavior to the following. <ServiceBehavior(
InstanceContextMode:=InstanceContextMode.Single,
ConcurrencyMode:=ConcurrencyMode.Multiple)>

B.
Change the service behavior to the following.
<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>

C.
Require the clients use threads, the Parallel Task Library, or other mechanism to issue
service calls in parallel.

D.
Require the clients to use async operations when calling the service.
