Correct option is B
In engineering and manufacturing, tolerance refers to the permissible limit of variation in a physical dimension. For a hole, the tolerance is the difference between the maximum hole size and the minimum hole size. This range defines how much the actual size of the hole can deviate from the nominal (designed) size while still being acceptable for the intended application.
· Maximum hole size: The largest allowable diameter of the hole.
· Minimum hole size: The smallest allowable diameter of the hole.
The tolerance is calculated as: Tolerance = Maximum hole size - Minimum hole size.
