List the state of each output pin of a 7447 if RBI = 0, LT = 1, A 0 = 1, A 1 = 0, A 2 = 0, and A 3 = 1.

A. RBO = 0, a = 0, b = 0, c = 0, d = 1, e = 1, f = 0, g = 0
B. RBO = 1, a = 0, b = 0, c = 0, d = 1, e = 1, f = 0, g = 0
C. RBO = 0, a = 0, b = 0, c = 0, d = 0, e = 1, f = 0, g = 0
D. RBO = 1, a = 0, b = 0, c = 0, d = 0, e = 1, f = 0, g = 0
Answer» B. RBO = 1, a = 0, b = 0, c = 0, d = 1, e = 1, f = 0, g = 0
