The answer is (3)
Explanation:
We know that
Y = A . B + \( \overline{B.C}\)
(1) 0 to t1
A = 0, B = 0, C = 1
Y = 0 . 0 + \( \overline{0.1}\)
= 0 + 1 = 1
(2) t1 to t2
A = 1, B = 0, C = 1
Y = 1 . 0 +\( \overline{0.1}\)
= 0 + 1 = 1
(3) t2 to t3
A = 0, B = 1, C = 0
Y = 1 . 0 +\( \overline{0.1}\)
= 0 + 1 = 1
