Solution

The correct option is D Milk changing casein into calcium paracaseinate at 1 - 3 pH
Rennin curdles milk protein caseinogens, which is hydrolysed into casein. Rennin converts casein into solid calcium paracaseinate in presence of Ca $^{2 +}$ at pH of 1 - 3 so that pepsin can reduce it to smaller protein particles.
