A person eats plenty of rice but very few pulses, milk, eggs or other protein-rich foods. Which function may be affected most directly?

Answer: A. Building and repairing tissues

Protein-rich foods like pulses, milk, and eggs provide essential amino acids that the body needs to build, maintain, and repair muscles, organs, skin, and other tissues. While rice provides carbohydrates for energy, it is low in protein, leading to a deficiency that directly impairs the body's ability to grow new cells and repair damaged ones.
