6(a) and 6(b)

These both are done in circuitverse

6(c)

Here we can make 8-party line in the way which is similar to the 4-party line. That is by using 3-input 8 output decoders in that one is for selecting only a single taker and the other for selecting a single listener. Then we connect modules via shared bus. Its same like normal line, Here 2 3:8 we will use for talker and listener.

6(d)

The outputs of one decoder are called as one-hot, because exactly one is "Hot"(high) at a given time. If we do use one hot decoders then there will be multiple talkers and listeners, not good in terms of selective audience -speaker interaction. It will even invade the data security and privacy, And this may result in data corruption which will lead to damaging the circuit. If we do not use "ONE-HOT" decoder in the 4 channel line party circuit then there would be not a way to navigate who listens and talks through the shared bus and all the inputs will be scrambled. This destroys the entire circuit orientation.

6(e)

The one hot decoder creates multiple new variables, Then it is prone to create a big problem as there are many unique values making the connections. Using of gates further may result in propagation delay, This will result a error in the output because some values may change before it interacts to the value . It even causes multi-collinearity between the individual variables which will make our circuit less accurate . Then further in mass communication this will become even more complex and result in delays and glitches.
