If u and v are negative integers, which of the following statements must be true?
I. (-u)^v is positive.
II. (-u)^(-v) is positive.
III. u^(-v) is positive.  Select the correct option:
A) None
B) II only
C) I and II
D) I and III
E) I, II and III
Let's u = -2 and v = -3   I. (-u)^v = (2)^(-3) = 1/(2^3) --&gt; Positive   II. (-u)^(-v) is positive. = 2^3 --&gt; Positive   III. u^(-v) is positive. = -2^3 --&gt; Negative   Answer: I and II
