• C. Chicken hearts.
• D. Pork kidneys.

Answer: (B)

Verified step by step guidance

1. Understand the concept of hypervitaminosis A: This condition occurs when there is an excessive accumulation of vitamin A in the body, which can lead to toxicity. Vitamin A is a fat-soluble vitamin stored in the liver, and consuming foods with extremely high levels of vitamin A can cause this condition.
2. Recognize the dietary sources of vitamin A: Vitamin A is found in animal products such as liver, eggs, and dairy, as well as in plant-based sources like carrots and sweet potatoes (as beta-carotene). However, the liver of carnivorous animals is particularly rich in vitamin A.
3. Evaluate the options provided: Cow brains, chicken hearts, and pork kidneys are not known to contain extremely high levels of vitamin A. However, the liver of carnivorous animals is a concentrated source of vitamin A, making it the most likely food to cause hypervitaminosis A.
4. Consider the biological role of the liver: The liver is the primary storage site for vitamin A in animals. Carnivorous animals, which consume other animals, often have higher levels of vitamin A stored in their liver due to their diet.
5. Conclude that eating the liver of carnivorous animals poses the highest risk of hypervitaminosis A due to its exceptionally high vitamin A content compared to other organ meats.
