Final answer:
Vitamin A and vitamin D are the two fat-soluble vitamins that can cause toxicity if consumed in excess because they are stored in body fat.
Step-by-step explanation:
The two fat-soluble vitamins that can cause toxicity if given in excess are vitamin A and vitamin D. These vitamins are stored in body fat and can accumulate to toxic levels when consumed in large amounts. Vitamin A toxicity can lead to symptoms such as nausea, vomiting, headache, and keratomalacia, which includes dryness of the eye and skin. Likewise, vitamin D toxicity might result in hypercalcemia, which can cause a range of issues including bone pain and kidney problems. It's important to monitor the intake of these vitamins to avoid potential health risks associated with their excess.
