Answer 1

The correct option is B Three

Colostrum is a milky fluid that comes from the breasts of mammals during the first few days after giving birth to a young one, before true milk comes. It 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. So, this statement C is correct.
Beer is produced by the saccharification of starch and fermentation of the resulting sugar.
So, statement $D$ is incorrect.
Therefore, three statements are incorrect.
