The tangents at the end points of any chord through

(1,0)

to the parabola

y^2+4 x=8

intersect

View answer and explanation

Correct option: D

at

90^{\circ}

on

x-3=0

Option D (at

90^{\circ}

on

x-3=0

) is correct because the tangents at the endpoints of a focal chord intersect at right angles on the directrix.
