The vertices of a triangle are `[a t_1t_2,a(t_1 +t_2)]`, `[a t_2t_3,a(t_2 +t_3)]`, `[a t_3t_1,a(t_3 +t_1)]` Then the orthocenter of the triangle is: `(a) ` `(-a, a(t_1+t_2+t_3)-at_1t_2t_3)` `(b) ` `(-a, a(t_1+t_2+t_3) + a(t_1t_2t_3)` `(c) ` `(a, a(t_1+t_2+t_3)+at_1t_2t_3)` `(d) ` `(a, a(t_1+t_2+t_3)-at_1t_2t_3)`
