Solution

To answer this question, we need to know the resolution of the ADC (Analog to Digital Converter). The resolution of an ADC is the number of bits it uses to represent the analog input in digital form.

The options given suggest that the ADC could be either 12-bit (where the maximum value is 4095) or 16-bit (where the maximum value is 65535).

The ADC works by dividing the reference voltage range into discrete steps. Each step corresponds to a binary value. If we assume the reference voltage is 3.3V, then a direct 3.3V connection to the ADC pin would correspond to the maximum binary value.

So, if the ADC is 12-bit, the binary value would be 4095 (option a). If the ADC is 16-bit, the binary value would be 65535 (option b).

Without knowing the resolution of the ADC, we cannot definitively answer this question.
