None of the above
C
Correct answer
Explanation
In system interconnection category of wireless network, there will be a system, which acts as a master and all of its interconnected parts such as mouse, keyboard are called slave, so it is called master-slave paradigm. In this, a master is responsible for managing all the activities like broadcasting time, frequency limit etc.
