3-D Geometry for JEE Advance

A line $L_1$ with direction ratios $(-3,2,4)$ passes through the point A $(7,6,2)$ and a line $L_2$ with direction ratios $(2,1,3)$ passes through the point B $(5,3,4)$ . A line $L_3$ with direction ratios $(2,-2,-1)$ intersects $L_1$ and $L_2$ at C and D. Then C and D are:

1. $(1,10,10)$
2. $(-1,12,11)$
3. $(7,4,7)$
4. $(3,8,9)$

Details: There can be multiple correct answers. If your answer is choice 1 and 2 then type your answer as 12 (choices must be in ascending order).
