But in digital systems 0 to 1.5V is treated as logic 0 & 3.5V to 5V treated as logic 1.
So that why it is unacceptable.

I think it is not unexpectable. We need to know every component voltage range.

As karthik said, vl and vh values vary from manufacturer to manufacturer. Because, one manufacturer may design for one volategs but on that same voltages, no other manufacturer component doesn't work. So, it is unacceptable.

Am also agree with niranjan because in digital voltage in b/w 1. 5v to 3. 5v is unvaluable thats why it is unacceptable.

Voltage between vl and vh is not acceptable because the IC property is vary from one manufacturer to other.

Digital devices works on 0 and 1 only. i.e. for 0, the voltage range is VLmin-VLmax and for 1, its VHmin-VHmax. So, the gap between VLmax and VHmin means nothing to a digital system because its neither 0 nor 1. Its just a transition state.
That's why, this region is unacceptable for digital devices.
This question is from digital point of view, not from analog.

Which voltage they are talking about?

@Kishore is right answer, in digital electronics logic 0 and logic 1 are the two states, there is none others. Some students said 1.5 is treated as 0 and 3.5 is treated as 1, but even though the voltage is 3.5, then why you are taken it as 1 or 5v because it is unacceptable in digital electronics.

How many voltage that can take in?

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.
