When applying the $100\%$ rule to a sensitivity report, what condition must be satisfied for the information to be considered valid?

The sum of the ratios of the proposed changes to the allowable changes for multiple RHS values and OFC values must be greater than $1$ to ensure validity.

Simultaneous changes to both OFC values and RHS values are permitted, provided the individual changes do not exceed $50\%$ of the allowable change.

The $100\%$ rule ensures validity if the sum of the ratios of each proposed change to its allowable change is less than or equal to $1.$

Changes to both OFC values and RHS values can be applied simultaneously as long as the total change does not exceed $100\%.$
