Solution

The correct option is C Statement-1 is true, Statement-2 is false
Intersection of L1 and L3 is P=(2,2)
Intersection of L2 and L3 is Q=(1,2)
Now, Intersection of L1 and L2 is O=(0,0)
Equation of angular bisector of ΔOPQ will be (5+22)x=(52)y
In ΔOPQ, angle bisector of O divides PQ in the ratio of OP:OQ which is 22:5 but it does not divide triangle into two similar triangle.
Hence, option 'C' is correct.
