Hint: Dietary proteins are those proteins that are taken from the food to maintain the protein level of the body. Protein is an essential component that is required to do the biological activities of an organism. Proteins can be taken from various foods like meat, eggs, nuts, milk, etc.

Complete answer:
Protein is known as the basic body unit. It is required in every part like skin, bones, muscles, hair, eyes, etc of the body. Protein is required to make enzymes, hormones, and other essential biological compounds. It is necessary for every step of the biological reaction. There are at least 10000 proteins found in the body that are involved in various activities.
Each protein comprises specific and particular amino acids. These amino acids are joined by the peptide bond and form the protein. Protease and peptidase are responsible for the breakdown of proteins within the gastrointestinal tract into amino acids, tripeptides, and dipeptides. Generated amino acids are then used in the body for various purposes.
The best source of dietary protein for the vegetarian is milk. It is a liquid food that contains a high nutritional value and comprises animal origin. Milk is produced by the mammals (female) by the mammary glands to feed their babies. Milk contains protein 3.4 g per 100 gm.

Hence, the correct answer is option (C).
