You need to create an embedded component that is self-container. Data binding and controller logic need to be defined within that embedded component.

What type of binding between the parent component and the embedded component would you choose?
A . Tight coupling by explicit binding
B . Loose coupling by node reference binding
C . Loose coupling by inport and outport context mapping
D . Tight coupling by node reference binding

Answer: C
