Math Question

The statement " \( \cot \theta=\frac{12}{5}, \sec \theta=-\frac{13}{5} \), and the terminal point determined by \( \theta \) is in quadrant \( 4 " \) :
A. cannot be true because if \( \cot \theta=-\frac{12}{5} \), then \( \sec \theta=\pm \frac{13}{12} \).
B. cannot be true because \( 12^{2}+5^{2} \neq 1 \).
C. cannot be true because \( \cot _{\theta} \) must be less than 1 .
D. cannot be true because \( \sec _{\theta} \) is greater than zero in quadrant 4 .
