Answer: Option A
Step-by-step explanation: In simple words, backward induction refers to the process under which an individual starts analyzing a performance from the end results and go backward to the steps to determine where actually the actions went wrong.
This technique is generally used for analyzing complex subjects which requires high technology or knowledge. It helps the individuals to determine what actions should be rectified in future so that same problems would not occur again.
In the given case, Elly is willing to analyze the whole subject by starting right from the results. Hence we can conclude that she is using backward induction.
