Hi,
lets try the combined info as it can be seen clearly individually, both are insuff..

combined we are given four lines intersecting at one point and 2 sets of line are perpendicular to each other..
But what is still missing is the angle between these set of lines..
the two sets could be coinciding or at 45 angle..
insuff
E
