The right option is; A. carbohydrates
Carbohydrate is the most important energy source for the body and it is the macromolecule that provides a person with most of the energy that is needed for daily activities. The body breaks down and uses carbohydrates faster and easier. This makes carbohydrate a short term fuel source that provides the body's most immediate energy that is required for daily functions. Also the body prefers to use carbohydrate as fuel during some activities such as exercise. Sources of carbohydrate include brown rice, whole grains (barley, and oats), fruits and vegetables and beans.
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
