The denominator of the fraction $\frac{ 3 }{ 4.24}$ is the length of the hypotenuse of the right-angled triangle. Which of the listed trigonometrical quantities does NOT include the hypotenuse in its definition?

This should help you find the answer on your own. It is neither $\sin A$ nor $\cos A$

tan A?

Excactly ! $\tan A=\frac{ BC }{ AC }=\frac{ 3 }{ 3 }=1\neq \frac{ 3 }{ 4.24 }$
