Hi I am preparing for the ECAA exam and I came across this question in a past paper and I don't see why the correct answer is A, not C. Any help is appreciated.

Statement (2) fails. It claims that .

However, this is the same as saying:

(A)

x = -2, y = -1 disproves 1) (-2/-1 > 1 but -2 < -1)
y = -2, x = 1 disproves 2) (-2/1 < 1 but 1/-2 < 1)
x = 2, y = 1/4 disproves 3) (2*1/4 < 1 yet x > 1)
