Solution
The correct option is A A and G Same phase implies that the wave should have same frequency as well as same wavelength. But there are only two points in the given wave which satisfies the following condition, the point A and G are the wave producers as we can see that wave produced after A and G exactly match each other i.e. they are in phase.
