Answer: Option A

Solution(By Examveda Team)

Average pH of normal milk is 6.6.
Fresh milk has a pH of 6 and when it changes into curd the pH value will decrease because curd contains lactic acid.
Milk is an acid-forming food. Its pH level is below neutral at about 6.6 to 6.9, because it contains lactic acid.
