Find the coordinates of the focus, axis of the parabola, the equation of the directrix and the length of the latus rectum for the following : $ y^2=-8x$

Question

$\begin {array} {1 1} (A)\;focus (-2, 0) , Axis : y - axis, Equation \: of \: directrix : x-2=0, Length \: of \: the \: latus \: rectum : 8 \\ (B)\; focus (2, 0) , Axis : x - axis, Equation \: of \: directrix : x+2=0, Length \: of \: the \: latus \: rectum : 8 \\ (C)\;focus (0, -2) , Axis : y - axis, Equation \: of \: directrix : y-2=0, Length \: of \: the \: latus \: rectum : 8 \\ (D)\;focus (0, 2) , Axis : y - axis, Equation \: of \: directrix : y+2=0, Length \: of \: the \: latus \: rectum : 8 \end {array}$
