2nd, 3rd and 5th options are correct.

Step by step explanation:

We are asked to find which of the given operations involving complex numbers have solutions represented by point A on the graph.

We can see that point A lies on (1,-2i). Let us see which of our given expressions give us coordinates of point A.

1.

We can see that our 1st option is incorrect.

2.

We can see that our 2nd option is correct.

3.  

We can see that our 3rd option is correct.

4.  

Upon simplifying our expression we got which is not equal to coordinates of point A. Therefore, 4th option is incorrect.

5.

Upon simplifying our expression we got coordinates of point A. Therefore, 5th option is correct indeed.
