Pressure drag results due to
- AFormation of wakeCorrect
- BTurbulence in the wake
- CExistence of stagnation point in the front of a body
- DHigh Reynolds numbers
Solution
Concept
Pressure drag
Step-by-step solution
1. Separation forms a wake with low pressure at the rear.
Explanation
Pressure drag arises from the wake.
Why the other options are wrong
Stagnation point and Reynolds number are not the cause.
Shortcut
Wake → pressure drag.
Correct answer: A) Formation of wake
