We know that
in the IV quadrant
cos theta is positive
and 
sin theta is negative
so
cot theta=cos theta/sin theta--------> cot theta must be negative
sec theta=1/cos theta------> sec theta must be positive

therefore

the answer is the option
<span>A. cannot be true because sec(theta) is greater than zero in quadrant 4</span>
