aspirin, because it is a medicine that reduces pain
B
diet drink, because it tastes sweet but does not have calories
C
water, because most of the human body is made of water
D
beans, because they contain protein for muscle growth
Explanation: 

Detailed explanation-1: -Many different types of beans can be part of a diet for lean muscle gain. Popular varieties-such as black, pinto, and kidney beans-contain around 15 grams of protein per cup (about 172 grams) of cooked beans ( 33, 34, 35 ).

Detailed explanation-2: -Beans are also included in the protein food group because they supply a significant amount of amino acids. They’re often used as a meat substitute in vegetarian and vegan diets.

Detailed explanation-3: -Beans are high in amino acids, the building blocks of protein. There are 20 amino acids, and nine of these are essential. There are also two types of protein sources: complete and incomplete. Animal products, soy, and quinoa are all complete proteins, which means they contain all nine essential amino acids.

Detailed explanation-4: -“Beans and legumes are fiber-rich nutrient powerhouses and an excellent source of protein, ” says Hopsecger. “One serving (1/2 cup cooked) of beans provides about 7 grams of protein, the same as 1 ounce of meat.”
