M = (-) x (-) x (-) x (-) x (-) x (-) x (-) = -ve
N = (-) x (-) x (-) x (-) x (-) x (-) x (+) = +ve
I. MN < 0: YES
(-ve)(+ve) = -ve
II. M - N < 0: YES
(-ve) - (+ve) = (-ve)
III. N + M <0: Can't Say
Since we don't know if the absolute value of N is more than the absolute value of M or not!
Hence, option C
N = (-) x (-) x (-) x (-) x (-) x (-) x (+) = +ve
I. MN < 0: YES
(-ve)(+ve) = -ve
II. M - N < 0: YES
(-ve) - (+ve) = (-ve)
III. N + M <0: Can't Say
Since we don't know if the absolute value of N is more than the absolute value of M or not!
Hence, option C
