Best answer
Correct answer is (d) Arduino Uno

The explanation: The analogReadResolution() function is used to change the resolution of the ADC for reading a particular voltage and mapping it to the number set. The resolution of the ADC is the number of levels up to which the ADC can quantize the analog Signal. The Arduino Uno is not capable of executing that command.
