Answer:
A. by showing the effects of changes to the original data or an underlying assumption
Explanation:
Sensitivity analysis refers to the process of determining the number of variation that exist in a system as a response towards specific ranges of inputs. It involves predicting how a system determines how dissimilar values of an independent variable affect a distinct dependent variable under a given set of conditionss, thereby focusing on dependent variable when various parameters changes. It helps in analyzing different values of a set of independent variables affecting a specific dependent variable under set conditions.
