Correct Answer : Option (C) : lower deviation
Explanation : In the context of geometric dimensioning and tolerancing (GD&T), the lower deviation of a hole is defined as the difference between the minimum limit of the hole size and its actual size.
It means the algebraic difference between the minimum limit and the basic size is called Lower deviation.
It's important to note that these terms are used in the context of geometric dimensioning and tolerancing (GD&T) and should be used in conjunction with the other GD&T symbols and concepts to ensure that parts are manufactured and assembled to the desired specifications.
