Sorry if this is posted in the wrong section.
But I came across this question on a test:
Which of the following will evaluate to true only if boolean expressions A, B, and C are all false?
(a) !A && !(B && !C)
(b) !A || !B || !C
(c) !(A || B || C)
(d) !(A && B && C)
(e) !A || !(B || !C)
I think the answer should be "d" but the correct answer seems to be "c" but I don't see why. Can anyone explain this?
Any help is appreciated.
