Correct Option
The correct option is (d).
Explanation
Food sources are broadly classified into two categories based on their origin: plant products and animal products. Animal products are substances derived from the body of an animal or produced through their physiological processes. This includes meat, eggs, milk, and secretions such as honey.
Statement-wise Analysis
- 1. Milk: Correct. Milk is a liquid food produced by the mammary glands of mammals (such as cows, buffaloes, and goats). It is a primary animal product.
- 2. Ghee: Correct. Ghee is clarified butter derived from milk fat. Since its primary source is milk (an animal secretion), it is classified as an animal product.
- 3. Curd: Correct. Curd is obtained by the coagulation or fermentation of milk. As a derivative of milk, it falls under the category of animal products.
- 4. Honey: Correct. Honey is a sweet, viscous food substance made by honey bees and some related insects. Bees collect nectar from flowers and transform it through enzymatic activity and evaporation within their hives. Although the raw material (nectar) is from plants, the final product is synthesized and stored by animals (insects), making it an animal product.
Key Takeaway: Any food item derived directly from an animal (like meat or milk) or processed by an animal (like honey) is classified as an animal product, distinct from plant parts like roots, stems, leaves, or fruits.
