Question 34 Not yet answered Marked out of 3.00 p Flag question Given the following digital circuit, which of the following statement is incorrect? A B IT X С Select one: A. If A = 0, B = 0, C =1, the output X is 0 B. If A = 0, B = 1, C =1, the output X is 0 C. If A = 1, B = 0, C =1, the output X is o D. If A = 1, B = 0, C =0, the output X is 0 E. If A = 0, B = 1, C =0, the output X is 0
