Options:
  • A $x^{2}=4(y-2)$
  • B $(\mathrm{y}-2)^{2}=4 \mathrm{x}$
  • C $y^{2}=4(x-2)$
  • D $(x-2)^{2}=4 y$

The correct answer is: $y^{2}=4(x-2)$
Since, the parametric equation $x=t^{2}+2$ and
$$
\begin{array}{ll}
y=2 t . & \\
\therefore & x-2=t^{2} \\
\Rightarrow & x-2=\frac{y^{2}}{4} \\
\Rightarrow & y^{2}=4(x-2)
\end{array}
$$
