What scale is useful to record the force of wind ?

The correct answer is C. Beaufort.

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. It was devised in 1805 by Sir Francis Beaufort, the Hydrographer of the Royal Navy, for use by sailors. The scale is logarithmic, with each whole number increase in wind speed representing a tenfold increase in wind speed. The scale is divided into 12 categories, from 0 (calm) to 12 (hurricane).

The Beaufort scale is used by meteorologists, sailors,
