A. Carbohydrates
B. Proteins
C. Ascorbic acid
D. Calcium hydroxide

Answer 1

Hint: Soybeans belong to the family Fabaceae and are used as a source of food as it provides certain macronutrients as well as micronutrients to the body. Eggs are also consumed by human beings to meet the requirements of certain nutrients, specifically macronutrients.

Complete answer:
-Option (A) is incorrect. Carbohydrates are also present in soybeans and eggs but in a lesser amount as compared to proteins. Carbohydrate-rich foods include bread, potatoes, berries, broccoli, etc. Thus, soybeans and eggs are not rich in carbohydrates.
-Option (B) is correct. Soybeans and eggs are rich in proteins. 100 g of soybeans contain about 36 g of protein while 100 g of the boiled egg contains about 13 g of proteins. Egg white contains the protein albumin. Other protein-rich food includes meat, fish, lentils, yogurt, nuts, etc.
-Option (C) is incorrect. In soybeans, ascorbic acid or vitamin C is present but in lesser quantity, as compared to the protein content, and in eggs, all the vitamins are present except the ascorbic acid or vitamin C. Thus, soybeans and eggs are not rich in ascorbic acid.
-Option (D) is incorrect. Soybeans and eggs are not rich in calcium hydroxide or slaked lime. Calcium hydroxide is a salt that can be used during the fractionation of soy protein and in the case of eggs; this salt can be used for preserving the eggs. Thus, soybeans and eggs are not rich in calcium hydroxide.

Hence, the correct option is (B).

Note: The scientific name of soybeans is Glycine max. It is a leguminous plant and is a rich source of protein. Other nutrients like carbohydrates, vitamins, minerals are also present but in a lesser amount as compared to its protein content. Eggs are also a rich source of protein and it has two components egg yolk and egg white that are a rich source of protein and consuming both the parts of an egg can meet the requirement of proteins by our body.
