Hint: Aneroid term is used to indicate ‘without fluid’. They are used to measure the atmospheric pressure. The working principle of an android barometer can tell the function of a flat spring. The compression and expansion of the mechanical instruments involved in the device used to read the variation in atmospheric pressure.
Complete Step-by-Step solution:
Aneroid barometers are also used for the measurement of pressure of the atmosphere. But it doesn’t contain any fluids as other barometers. It needs complex machinery systems for accurate readings. The compact design, stability and easy to transport made them satisfactory devices.
In this device a flat spring and couple of hair springs can be found. The flat spring is used to prevent the diaphragm from collapsing with other machinery systems. Since the diaphragm will expand or contract according to the atmospheric pressure. So, the correct option is C. To understand the working principle, you can observe the following aneroid barometer diagram.

Additional information:
Aneroid barometer contains a small, flexible metallic box, which is made up of beryllium and copper and known as aneroid capsule. This metal box is tightly sealed. So, the atmospheric pressure either pushes inward or pulls outward. Hair like springs are connected with this metallic box. Thus, the spring will expand or contract according to the pressure acting on the box. This movement can be measured instantly by using a pointer attached with a reader. However, an aneroid barometer is not that much accurate as a mercury barometer.
Mercury barometer handling is not that much easy because of its size and fragile materials. But it can be constructed easily.
Note: Aneroid barometer is sensitive to the temperature variations. But it is avoided by the usage of bimetallic strips. It will expand according to the temperature. So, no frictional problems will rise. The flat spring is also used to avoid the frictional resistance. The other options in the given question are opposite to the function of aneroid barometer.
