Answer:
As we know sum of exterior angle of any polygon is 360°.
So, a Regular hexagon has 6 sides and measure of each exterior angle will be same.
Let us suppose that each exterior angle of regular hexagon be X°.
As each interior angles of regular hexagon are same as well as each exterior angle of regular hexagon is same.
There are 6 exterior angles in regular hexagon.
So,→ X+ X+X+X+X+X=360°
→ 6 X= 360°
X=360°÷ 6
X = 60°
Option A . 60° is correct answer ,i.e the measure of each exterior angle of a regular hexagon
