• C. Only assertion is true
• D. Both assertion and reason are false

Answer 1

The correct option is A Both assertion and reason are true and the reason is the correct explanation for the assertion

Curd is a fermented food product that is commonly prepared in our household for its health benefits. It is formed by the fermentative action of lactic acid bacteria (LAB) on milk. For preparing curd, a little amount of curd containing lactic acid bacteria is added as an inoculum into milk and kept at a warm temperature overnight.

One of the reasons curd is considered very nutritious is because the lactic acid bacteria in it secretes Vitamin $B_{12}$.
Vitamin $B_{12}$is required by the body for the maturation of red blood cells. Its deficiency can result in pernicious anaemia.

Thus, both assertion and reason are true and the reason is the correct explanation for the assertion.
