Answer:
1st option: G, H, I
Step-by-step explanation:
Collinear points are points that lie on the same straight line.
In the diagram, the collinear points are:
• L, H, J
• G, H, I, K
For the 2nd option, I does not lie on the same straight line as L and H.
For the 3rd option, J does not lie on the same straight line as G and H.
For the 4th option, J does not lie on the same straight line as G and I.
Thus, the 2nd, 3rd and 4th options are incorrect.
