Solution
The correct option is C 12
In the figure above, three lines k, l and m intersect each other at three points A, B, and C.
Total angles formed at point A = 4. (As shown in the figure)
Similarly, four angles are formed at points B and C.
Hence, the total number of angles that are formed when three lines intersect at three points = 4 + 4 + 4 = 12
