Question

Read the following four statements (A-D).

(A) Colostrum is recommended for the newborn, because it is rich in antigen.
(B) Chikungunya is caused by a Gram-negative bacterium.
(C) Tissue culture has proved useful in obtaining virus-free plants.
(D) Beer is manufactured by the distillation of fermented grape juice.

How many of the above statements are wrong?

• A. Three
• B. Four
• C. One
• D. Two

Answer 1

The correct option is A Three

• 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. So, statement D is incorrect.

Thus, the number of incorrect statements are 3. Hence, the correct answer is option A.
