Answer:
Step-by-step explanation:
Approximate angles of sectors shaded:
- A - 1 quarter = 90°
- B - 1 quarter + third of quarter = 90° + 30° = 120°
- C - 1 quarter and half = 90° + 45° = 135°
- D - 1 quarter and half and third = 90° + 45° + 30° = 165°
- E - 2 quarters = 180°
Full circle if 360°, so its third is 1/3*360° = 120°. This matches the option B.
The answer is B
