Break-even analysis can be defined as: O (a) Analysis of the amounts by which one input variable must fall before a project ceases to create wealth. O (b) Analysis of the amount by which the NPV falls when one input variable is changed from its optimistic to its pessimistic forecast. O (c) Analysis of the effect of simultaneously changing all of the input variables whose values are uncertain to observe the effects on the results. O (d) Analysis of the effect of the correlation of the input variables on the project's NPV. O (e) None of the above
