Correct Answer - Option 2 : 120°

**Given:**

In a regular polygon, each interior angle measures 60°.

**Formula used:**

In a regular polygon, Interior angle + Exterior angle = 180°.

**Calculation:**

Let the measure of each exterior angle be E°

⇒ 60° + E° = 180°

⇒ E° = 120°

∴ Measurement of each exterior angle of the polygon = 120°
