The sum of all the exterior angles in a polygon is equal to:

A. 390
B. 360 
C. 340
D. 300

🧠 Explanation (Math):

Given: Sum of all exterior angles of a polygon
Step 1: Exterior angles taken one at each vertex always sum to a constant
Step 2: That constant is independent of the number of sides
Step 3: The constant sum equals 360 degrees
Final Answer: 360
