Which of the following is a common source of dietary cholesterol?

Dietary cholesterol is a type of cholesterol that is obtained from animal-based foods, as it is primarily found in the cells of animal tissues. Eggs are one of the most significant sources of dietary cholesterol, with the yolk containing a high concentration of cholesterol. Consuming eggs contributes to daily cholesterol intake, which can be a concern for individuals managing their blood cholesterol levels or those who are advised to limit cholesterol intake for health reasons.

In contrast, leafy greens, whole grains, and nuts are plant-based foods and do not contain cholesterol. While they are excellent sources of various nutrients, including fiber, vitamins, and healthy fats, they do not contribute to dietary cholesterol levels. Therefore, eggs stand out as the only option among the ones listed that provides a significant amount of dietary cholesterol.
