Solution

The correct option is C 0.1 Hz
Researchers have found that pigeons can hear a sound as low as 0.1 Hz. This feature makes them highly alert and gives them the power to detect thunderstorms, earthquakes, magnetic storms or any other climatic activity. The very low-frequency sound (aka infrasound) can travel thousands of kilometres without any distortion.
Hence, the correct answer is '0.1 Hz'.
