Margarine is a substitute for butter and is insoluble in water. However, margarine is soluble in turpentine. Margarine is solid at room temperature and metabolizes to produce high calories. Given these properties, margarine is most likely an example of a(n) .

Oil derivate / lipid

Explanation:

Margarine is obtained by hydrogenating (or also esterifying) vegetable oils, such as soy, sunflower or corn.

As it belongs to the lipid class, margarine is solid at room temperature and can be metabolized by animal cells to produce energy(calories).

Turpentine is a liquid substance, generally used as a solvent in mixtures of oils, paints and varnishes.

According to these properties, it can be concluded that margarine is soluble in turpentine because it is an example of an oil derivative(lipid).

Fat

Explanation:

Fats are types of lipid which are solid at room temperature. Chemically it contains  varied  long chains of bonded Carbons and Hydrogen, and these made them to be insoluble in water  (Hydrophobic) . But are soluble   in like -organic solvent and some chemical solvent  like turpentine.

The nature of bonds in lipids is related to the action and storage of fats as micro molecules. Thus fats with double bonds are said to be unsaturated and therefore not good for health, but help in fluidity in  bacteria. Fats without  double or triple bonds are said to be saturated and therefore called good fats.Saturated fats are well packed with layers of C-H bonds well arranged which enhance  resistance at room temperature.

Generally margarine is made contains unsaturated good fats, made from vegetable oils.

Examples of fats are cholesterol, triglycerides etc.
