Solution

The correct option is B Do not require header

In synchronous transmission data from various users Do not require header.

There are many serial data transfer protocols. The protocols for serial data transfer can be grouped into two types: synchronous and asynchronous. For synchronous data transfer, both the sender and receiver access the data according to the same clock. Therefore, a special line for the clock signal is required.

Synchronous transmission is a data transfer method which is characterized by a continuous stream of data in the form of signals which are accompanied by regular timing signals which are generated by some external clocking mechanism meant to ensure that both the sender and receiver are synchronized with each other.
