Pick out the wrong statement about cavitation.

• A. Sudden reduction of pressure in a fluid flow system caused by flow separation, vortex formation or abrupt closing of valve leads to cavitation.
• B. Cavitation may be caused due to boiling of liquid by decreasing the pressure resulting in formation & collapse of vapor cavities.
• C. Cavitation begins at higher static pressure and lower velocity in larger diameter pipelines resulting in audible noise.
• D. Large scale cavitation can not damage pipeline, restrict fluid flow and damage steam turbine blades.
