The correct answer is B. high.
An OR gate is a digital logic gate that implements logical disjunction (inclusive OR). It produces a high output (1) if any of its inputs are high (1), and a low output (0) if all of its inputs are low (0).
Option A is incorrect because the output of an OR
gate is high if any input is high, not low.Option C is
incorrect because the output of an OR gate is not always 0. It is only 0 if all of the inputs are low.Option D is incorrect because only one of the options is correct.
Option E is incorrect because the output of an OR gate is high if any input is high, not low.
