与普通方程x²＋y－1＝0等价的参数方程是(   )

A：$\left\{\begin{array}{c}x=\cos \theta \\ y={\sin }^2\theta \end{array}\right.$(θ为参数)

B：$\left\{\begin{array}{c}x=\sin t\\ y={\cos }^{2}t\end{array}\right.$(t为参数)

C：$\left\{\begin{array}{c}x=\sqrt{1-t}\\ y=t\end{array}\right.$(t为参数)

D：$\left\{\begin{array}{c}x=\tan \phi \\ y=1-{\tan }^2\phi \end{array}\right.$(φ为参数)
