Which type of fried eggs have broken yolks?

The correct choice refers to over hard eggs, which are characterized by fully cooked yolks that have been broken and cooked through. When preparing over hard eggs, the egg is flipped during the cooking process, allowing the yolk to break and cook all the way until it reaches a solid state. This method results in a firm yolk rather than a runny or soft one.

In contrast, sunny-side up eggs are cooked on one side only, leaving the yolk intact and runny. Over easy eggs also involve flipping the egg, but the yolk remains partially runny. Similarly, over medium eggs have a yolk that is partially cooked but still retains some softness. Therefore, the essential characteristic of over hard eggs is their fully cooked, broken yolk, which distinguishes them from the other cooking styles where the yolk retains some level of softness.
