Units of surface tension are

Answer & Solution
Correct Answer: Option A
Surface tension is indeed a measure of the energy required to increase the surface area of a liquid by a unit amount, and it is commonly expressed in units of energy per unit area (such as N/m or dyn/cm). Option B (distance) is not correct, and option C (both of the above) is not accurate in this context. So, for the specific field of Hydraulics and Fluid Mechanics, the correct answer is option A.
