Question

................ is the best source of protein.

• A. Meat, Fish and Egg
• B. Vegetables
• C. Rice
• D. All of these

Hint:

When a question asks for the "best source" of protein, animal-based foods are generally the expected answer due to their high concentration and complete amino acid profiles. For plant-based protein, soyabeans and quinoa are notable exceptions as complete proteins.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The question asks to identify the best source of protein among the given options. "Best" in this context usually refers to both the quantity and quality (completeness) of the protein.
Step 2: Detailed Explanation:
Let's compare the options:
(A) Meat, Fish and Egg: These animal products are considered high-quality protein sources. They are protein-dense and contain all nine essential amino acids that the human body cannot produce on its own, making them "complete" proteins.
(B) Vegetables: While many vegetables contain protein, the concentration is generally much lower than in animal products. Also, most vegetable proteins are "incomplete," meaning they lack one or more essential amino acids.
(C) Rice: Rice is primarily a source of carbohydrates. Its protein content is very low.
Step 3: Final Answer:
Meat, fish, and eggs are the best sources of high-quality, complete protein among the choices provided.
