All of these choices are accurate. Consumption of lactose increases calcium absorption because lactose helps in the digestion and absorption of other nutrients in the small intestine, which creates a better environment for the absorption of calcium. An acidic environment in the duodenum helps in the solubilization and ionization of calcium, which makes it more available for absorption. 1,25 (OH)₂ vitamin D increases calcium absorption by stimulating the production of calcium-binding proteins in the intestinal cells, which promote calcium uptake.
