All of the following are true with the respect to implicitinvocation except:
a. it is based on the notion of bradcasting b. it is event-driven c. data exchange usesrepository d. components are instances ofabstractions

D) components are instances of abstraction

Explanation:

As, implicit invocation is the process by which it is used by the the software designer for styling the architecture of the software,where the event handling structured are formed in the system. The main aim of the implicit invocation is to separated the conceptual concern for maintaining or improving the ability of the software engineer. It is basically based on the notion of the broadcasting and based on the event driven. The components are the instance of the abstraction which are not used as the components in implicit invocation which are relinquished control the system over the computational performance,this is the major disadvantage of the implicit invocation.
