- pumpkin and carrots
- tomato and onion
- pepper and potato
- green peas and beans
The Correct Option is A
Solution and Explanation
Vitamin A is a fat soluble vitamin that helps in maintaining vision. Carrot is one of the best sources of vitamins and minerals especially Vitamin A. Deficiency of Vitamin A causes night blindness. The active form of Vitamin A is Retinoids. It helps in vision and skin health. Vitamin A also has antioxidant activity and helps in cellular communication.
Pumpkin and carrots are the richest source of vitamin A.
So, the correct answer is (A): pumpkin and carrots

Biomolecules
Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
- Carbohydrates are chemically defined as polyhydroxy aldehydes or ketones or compounds which produce them on hydrolysis.
- Proteins are another class of indispensable biomolecules, which make up around 50per cent of the cellular dry weight. Proteins are polymers of amino acids arranged in the form of polypeptide chains. The structure of proteins is classified as primary, secondary, tertiary and quaternary in some cases.
- Nucleic acids refer to the genetic material found in the cell that carries all the hereditary information from parents to progeny. There are two types of nucleic acids namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The main function of nucleic acid is the transfer of genetic information and synthesis of proteins by processes known as translation and transcription.
- Lipids are organic substances that are insoluble in water, soluble in organic solvents, are related to fatty acids and are utilized by the living cell.
