- AGravitational force
- BCentrifugal force
- CFrictional force
- DPressure gradient force
Explanation
The pressure gradient force is the primary driving force that sets air in motion from high to low pressure and determines wind velocity (NCERT Class XI Geography, Chapter 9); the source page's key misprinted this as (c), corrected against multiple independent keys for this exact CAPF 2011 question.
