Answer :

Given equation of the parabola is y2 + 8x - 2y + 17 = 0



y2 - 2y + 17 = - 8x


y2 - 2y + 1 = - 8x - 16


(y - 1)2 = - 8(x + 2)


Comparing with standard form of parabola (y - a)2 = - 4b(x - c) we get,


4b = 8


We know that the that the length of the latus rectum is 4b.


The correct option is C
