0 to 1.5 logic 0.
1.5 to 3.5 is unacceptable.
3.5 to 5 logic 1.
If the value of voltages lies between 2 to 3 is known as unacceptable.

In this world of semiconductor, anything above VL (max) and below VH (min) is unacceptable, because that is called state of uncertainty.
It has to do with noise margins and fabrication defects. VL (max) is acceptable noise margin for low state, VH (min) is acceptable noise margin for high state.
Actual voltages may differ from implementations to designs and fabrication methods.

Generally In digital logic design there are voltage and current parameters defined so regarding to these parameters it is described that the voltage range between the Vlmax and VHmin in unacceptable i.e it is neither 1 nor 0.

Normally looking at the options. Option A is not ok because voltages are known and can be measured. Option B Is not ok because all measurable quantity has it's significance. Option D cannot be because we observe less than 2 volt while measuring and 1.5 we do work as low limit. So, would like to go for Option C, because we always go for 0 and 1 in digital electronics so min and max limit are unacceptable.

It won't make sense if set max and min voltages without knowing circuit components so acceptable.

There is something called strong 0 and weak 1. Could that be related here, because a voltage near to 5V say 4.8V is treated as strong 1.

Why it is unacceptable?

I think in digital by quantization.
We make that level of supply according to our device.
Generally its 0/5 volt.

My question is if value vary from manufacture then its value should be unknown, why it is not acceptable? If in any IC value matches then what?

It is unacceptable because of emitter current is zero.
