ANSWER AND EXPLANATION:
The correct answer is C
Explanation: Don't get carried away by choice B. Sensitivity Analysis is a risk analysis technique not a risk identification technique. It is not a sampling technique or a distribution. In Design of Experiments one studies the effect of some process or intervention (the treatment) on some objects (the experimental units). In Sensitivity Analysis one looks at the effect of varying the inputs of a mathematical model on the output of the model itself. In both disciplines one strives to obtain information from the system with a minimum of physical or numerical experiments.
