The correct answer is: A. U-tube with water.
A U-tube manometer is a simple device used to measure pressure differences. It consists of a U-shaped tube filled with a liquid, such as water or mercury. When pressure is applied to one side of the tube, the liquid will rise on that side. The difference in the height of the liquid on the two sides of the tube is proportional to the pressure difference.
The sensitivity of a manometer is determined by the density of the liquid used and the size of the tube. A U-tube manometer with water will be more sensitive than a U-tube manometer with mercury because water has a lower density. The size of the tube also affects the sensitivity of the manometer. A larger tube will be less sensitive than a smaller tube.
An inclined U-tube manometer is a type of U-tube manometer that
