Solution:

Colostrum is a milky fluid that comes from the breasts of mammals the first few days after giving birth before true milk comes and is rich in proteins, carbohydrates, fats, vitamins, minerals, and antibodies (not antigens). So, statement A is incorrect. Chikungunya is caused by the chikungunya virus (not bacteria). So, statement B is incorrect. Tissue culture has proved useful in obtaining virus-free plants. This is correct. Beer is produced by the saccharification of starch and fermentation of the resulting sugar.
