D)Artificially acquired passive immunity

Answer 1

Hint:Colostrum is breast milk secreted by mammals after the birth of a young one.Its has the capacity to develop immunity from childhood itself.

Complete answer:
Colostrum is a nutrient-rich fluid produced by female mammals immediately after giving birth. It is loaded with immune, growth and tissue repair factors. It is a complex biological fluid produced by the mammary glands which helps in the development of immunity in the newborn. It contains significant quantities of complement components that act as natural antimicrobial agents to actively stimulate the maturation of an infant’s immune system.
Colostrum contains immunoglobulins (Ig) and antimicrobial peptides (lactoferrin and lactoperoxidase) and other bioactive molecules, including growth factors which are important for nutrition, growth and development of the newborn. A big percentage of the initial immunity developed in the body of a new born child is due to the intake of colostrum. That is why women are advised to feed their babies with their own breast milk for at least the first 3 months. Consumption of colostrum produced by dairy farm animals like cows, buffaloes, camels, sheep, and goats has also proven beneficial for building the immunity of both kids and adults.
The baby gets the colostrum when it feeds on the mother's breasts. It is naturally occurring and is passively transferred to the infant. The immunity factors acquired by the colostrum help in developing the active immune system.
Hence it is a naturally acquired passive immunity.

Hence the correct answer is option (B.)

Note:Colostrum has various health benefits and has been used in ayurvedic treatments for years.
