Which of the following options must be true given the equation p=-q^6
I. If q is negative then p is negative.
II. q is negative.
III. q is non-negative. Choose the correct choice:  A) I only  B) II only  C) III only  D) II and III only  E) I and III only
I. p is negative --&gt; not necessarily true, if q=0 then p=-q^6=0;   II. q is non-negative. q can take ANY value: positive, negative, zero. We don't have any restrictions on its value;   III. If q is negative then p is negative. p is negative means that q is not zero.   I onlynswer: I only (I only).
