I think that the values are not necessary as the circuit operates for either max or min with acceptable errors.

I think it related to Noise Margin. So analyse the question right to noise margin.

Why can't it is unknown.

Digital circuits are mainly for "low power applications".
So, as Jigar said manufacturer have a requirement to make an IC in which 1-means a high voltage level (Vdd) similarly 0 for low voltage (some. X). That Vdd and x depends on requirement and transistor technology in which IC is manufacturing (channel length).
So the answer is C.

Answer is C.

Since it is digital that's why no varying value is acceptable thus answer is unacceptable for digital circuits.

I can't understand. Please explain it briefly.

I think the right answer should be C. Agree with the given answer.

It's not about real voltages. In an ideal world, Digital circuits will have one single high voltage for 1 and another single low voltage for 0. All others are not allowed. Two voltage levels for two symbols. However this is not possible due to noise and hence we consider small ranges for both. So, ideally option C is correct.

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.
So that why it is unacceptable.
