Formation of urine is mainly related to which process?

Answer and explanation

Correct answer: Filtration of blood

Urine formation is a part of excretion, a life process that removes metabolic wastes from the body. Blood enters the kidneys, where nephrons filter it and selectively reabsorb useful substances and some water. The remaining wastes, excess salts and water form urine. Therefore, option A is correct; chewing, air entry and light capture belong to digestion, respiration and photosynthesis, not urine formation.
