Q. Why tolerances are given to the parts?

(A) because it’s impossible to make perfect settings
(B) to reduce weight of the component
(C) to reduce cost of the assembly
(D) to reduce amount of material used
Correct : Option (A)

Explanation: 
 tolerances are provided to the parts because variations in the material properties introduce errors and production machines themselves have inherent inaccuracies. another reason to introduce tolerance is that it is not possible to make perfect settings by operator so some tolerances are provided.
