None of the above

Explanation:
Detailed explanation-1: -The logic gate truth table is as follows: AND: True if A and B are both true. OR: True if A or B are true. XOR: True if either A or B are true, false if both are true.
Detailed explanation-2: -The OR gate gets its name from the fact that it behaves after the fashion of the logical inclusive “or.” The output is “true” if either or both of the inputs are “true.” If both inputs are “false, ” then the output is “false.” In other words, for the output to be 1, at least input one OR two must be 1.
Detailed explanation-3: -The Boolean expression of the OR gate is Y = A + B, read as Y equals A ‘OR’ B.
