B Correct answer
Explanation

The white arc on an airspeed indicator marks the flap operating range, showing the speeds at which flaps may be safely extended. The lower end indicates the speed at which flaps can be fully extended, while the upper end shows the maximum speed with flaps deployed. This range is critical for safe flap operation during approach and landing.
