The expression $\frac{\sin ^{2} A}{\tan A}$ is equivalent to 1) $\frac{\sin A}{\cos A}$ 2) $\sin A \cos A$ 3) $\frac{1}{\sin A \cos A}$ 4) $\frac{\cos A}{\sin A}$

Step 1 ：Given expression: \(\frac{\sin^2 A}{\tan A}\)

Step 2 ：Substitute \(\tan A = \frac{\sin A}{\cos A}\) in the expression: \(\frac{\sin^2 A}{\frac{\sin A}{\cos A}}\)

Step 3 ：Simplify the expression: \(\sin A \cos A\)

Step 4 ：\boxed{\sin A \cos A}
