Answer 1

Hint: Gelatin is explained as a translucent, colourless, flavourless protein which is derived from collagen fibres from various animal raw materials. It is also commonly used as a gelling agent in food, drugs, photographic emulsion, and cosmetic manufacturing.

Complete answer:
Gelatin is a type of protein that is obtained by boiling skin, tendons, ligaments, or bones with water. Usually it is obtained from cows or pigs.

Gelatin is also eaten in foods, because it is considered safe by the FDA( Food and Drug Administration ). Some of the experts say that gelatin has a risk of being contaminated with certain animal diseases. But So far there have been no reported cases of people getting sick in this way.

Gelatin has a unique amino acid profile that gives it many potential benefits for our health. Some experts say that gelatin may reduce joint and bone pain, increase brain function and help reduce the signs of skin aging.

Let us see how gelatin is made from animals Gelatin is made from the decaying animal hides, crushed bones , and the connective tissues of cattle and pigs are boiled. Gelatin processing plants are usually located near slaughterhouses, and often the owners of gelatin factories have their own slaughterhouses where animals are killed just for their skin and bones.

Hence, the correct answer is option (C).

Note: The traditional marshmallow recipe uses powdered marshmallow root, but most commercially manufactured marshmallows instead use gelatin in their production. Vegans and vegetarians avoid gelatin, but there are versions which use a substitute non-animal gelling agent such as agar.
