Answer:
Among the options given on the question the correct answer is option C.
can move out of proper location , causing leakage.
Explanation: A gasket is a mechanical seal or lock which is used for filling the space between two or more mating surfaces to prevent the leakage or to prevent the mixing of the components under the compression.
They are commonly produced by cutting sheet materials. They allow for almost perfect mating surfaces on machine parts to fill the irregularities.
However the surface of a gasket is very important to determine. Because the surface can not be too smooth or too rough. If the surface is too smooth than it can be slippery and will not have proper grip. As a result it can move out from the proper location.
As a result there will be leakage which hamper the machine parts.
On the other hand if the surface is too rough it will be hard for the gasket to conform to surface imperfection and also may have leakage.
