The correct answer is option 1: Phytosterols. Phytosterols are a group of plant compounds that are structurally similar to cholesterol. They are found in various parts of plants, including fruits, vegetables, nuts, and seeds. Phytosterols have a similar chemical structure to cholesterol, but they have slight differences that prevent them from being absorbed by the body like cholesterol.

Option 2, Calciferols, refers to a group of compounds including vitamin D.

Option 3, Ergocalciferols, refers specifically to a form of vitamin D derived from plants.

Option 4, Lumisterols, are a type of sterol found in certain organisms, but they are not related to plants.

In summary, phytosterols are the plant sterols that resemble cholesterol and are found in various plants. They have similar chemical structures to cholesterol but are not absorbed by the body in the same way.
