• A. 1 only
• B. 2 only
• C. Both 1 and 2

Answer 1

The correct option is A 1 only

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The irregularities of the earth’s surface offer resistance to the wind movement in the form of friction. It is greatest at the surface and its influence generally extends up to an elevation of 1 – 3 km. Over the sea surface the friction is minimal.
