Elections limit the power of the following types of governments:
- Dictatorship
- Oligarchy
- Totalitarian
Elections can help prevent concentrated, unchecked power typical of dictatorships and oligarchies, where a small group or a single leader holds significant authority. In totalitarian regimes, elections may be manipulated or non-existent, but the existence of genuine elections could limit the government's power over the populace.
Constitutional monarchy and constitutional republic typically have systems in place that include elections, which inherently limits the power of those in authority within those frameworks. However, since the question seems to focus on types of government that lack such mechanisms of accountability, the above three are the most accurate selections.
