Final Answer : A, Explanation :  The DC average voltage of a waveform is calculated by finding the area under the curve (which is the product of the voltage and the time it is at that voltage) and then dividing by the total period of the waveform. For a square wave with a 25 μs pulse at 12 V and a 75 μs gap (total period = 100 μs), the average voltage is (12 V * 25 μs) / 100 μs = 3 V.
