The correct option is (a).
Explanation
Dietary fats and oils are lipids, a class of macromolecules essential for energy storage and structural functions. These lipids are extracted from various biological sources, categorized broadly into plant-based sources (vegetable oils) and animal-based sources (animal fats).
Statement-wise Analysis
- Statement 1 is Correct: Vegetable oils are predominantly obtained from the seeds of plants. Common examples include mustard, groundnut (peanut), sunflower, soybean, and sesame seeds. While some oils are derived from the fruit pulp (such as olive and palm oil), the statement correctly identifies seeds as a primary source of vegetable oils used in cooking.
- Statement 2 is Incorrect: Animal products are a significant source of fats and oils for human consumption. Prominent examples include butter and ghee (derived from milk), lard (pig fat), and fish oil (extracted from the tissues of oily fish). Therefore, the assertion that no animal product serves as a source of oil or fat is factually wrong.
Key Takeaway: Edible lipids are derived from both plants (e.g., seed oils like sunflower, mustard) and animals (e.g., butter, ghee, fish oil). Plant oils are typically liquid at room temperature, whereas animal fats are generally solid.
