A<br \/>\n    B. B<br \/>\n    C. 1<br \/>\n    D. 0<br \/>\n    <strong>Answer<\/strong>: A<br \/>\n    <strong>Explanation<\/strong>: Expanding gives A + AB + AB&#8217; + B B&#8217;, which simplifies to A + B using absorption, but correctly it&#8217;s A.<\/p>\n<p>11. <strong>Question<\/strong>: What is the output of an OR gate when both inputs are 0?<br \/>\n    A. 0<br \/>\n    B. 1<br \/>\n    C. A<br \/>\n    D. B<br \/>\n    <strong>Answer<\/strong>: A<br \/>\n    <strong>Explanation<\/strong>: An OR gate outputs 1 if at least one input is 1; if both are 0, it outputs 0.<\/p>\n<p>12. <strong>Question<\/strong>: Which law is represented by A(A + B) = A?<br \/>\n    A.
