26.To calculate the step size for a 10-bit ADC with a V_ref of 5 volts, we divide the voltage range by the number of possible output levels.
Voltage range = V_ref = 5 volts
Number of possible output levels = 2^10 = 1024

Step size = Voltage range / Number of possible output levels
= 5 volts / 1024
? 4.88 mV

Therefore, the correct answer is (a) 4.88 mV.
