If a < 0 and b > 5, which of the following is true?
I. a * b > 0
II. a * b < 0
III. a^2 * b > 0 Choose one.
A) I only
B) II only
C) III only
D) I and III only
E) II and III only
I. Not true, example: a = -1, b = 6, so a * b = -6   II. True, since a is negative and b is positive, a * b is negative and the a * b &lt; 0   III. True, a^2 is positive and so is b so the product is positive   II and III only
