Why Do Changes in Institutional Design Alter Outcomes

Why do changes in institutional design alter outcomes?

A) Outcomes are outside the scope of institutions, and thus have no effect.
B) Outcomes are only possible to be changed through elections, and thus changes to election laws will produce much change.
C) Institutions are only collections of rules, and thus have no effect on outcomes.
D) Outcomes are determined by institutional structures and rules, and thus changing the institution changes outcomes.
E) Institutions are equal to outcomes; thus, changing one completely undermines the other.
