Solution

The correct option is D E(6,2)
Drawing ABCDE for each case, we find:

Case 1:E (2,4)


Case 2:E (4,6)


Case 3:E (7,5)


Case 4:E (6,2)


As we can see, only case 4 shows a single polygon with 5 sides and 5 vertices.

Hence, the only case where ABCDE forms a pentagon is when the coordinates of E are (6,2)
