What characterizes "sunny side up" eggs?

"Sunny side up" eggs are characterized by being cooked on one side only, which allows the egg whites to set while the yolks remain runny and intact. This method results in a beautiful presentation, where the bright, yellow yolks are visible and create an inviting appearance alongside the firm, white parts of the egg. Cooking them this way means that they do not get flipped over or cooked on both sides, preserving the liquid texture of the yolk while achieving a tender white.

The other cooking methods described in the other options completely change the nature of how the egg is prepared, resulting in different textures and appearances than what is typical for sunny side up eggs. For example, flipping the egg and cooking both sides would lead to a fully cooked yolk, which is not consistent with the sunny side up style. Similarly, scrambling eggs results in a completely different cooking process that mixes the yolks and whites, which would not produce the distinct visual and textural attributes of sunny side up eggs.
