Detailed Solution
(A) is wrong: colostrum, the yellowish milk secreted in the first few days of lactation, is rich in antibodies (IgA), not antigens; it gives passive immunity to the new born.
(B) is wrong: chikungunya is a viral disease transmitted by the $Aedes$ mosquito; it is not caused by a bacterium.
(C) is right: the meristem (apical and axillary) is free of virus even in an infected plant, so meristem culture gives virus-free plants, e.g., in banana, sugarcane and potato.
(D) is wrong: beer is produced from fermented malted cereals without distillation; fermented grape juice gives wine, and distillation of fermented broth gives whisky, brandy and rum.
Statements (A), (B) and (D) are wrong, so three statements are wrong.
