As shown in figure "A" of the illustration, what input conditions are required to produce an output? Illustration EL-0241
AI Explanation
The correct answer is B) Either "Input 1" or "Input 2" must be closed OR both "Input 3" and "Input 4" must be closed.
This is the correct answer because the logic gate shown in the illustration is an OR gate. For an OR gate, the output will be produced if either one or more of the inputs are closed (active). So, either "Input 1" or "Input 2" can be closed to produce the output, or both "Input 3" and "Input 4" must be closed to produce the output.
The other answer choices are incorrect because they describe different logic gate configurations that do not match the OR gate shown in the illustration.
