(b) Chikungunya is caused by Gram (-) bacterium
(c) Tissue culture is useful in obtaining virus free plants
(d) Beer is obtained by distillation of fermented grape juice

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

Answer 1

The correct option is C Three

Colostrum :
Colostrum is the secretion of the mammary glands at the initial stage of lactation. This secretion is rich in antibodies that confers some immunity to the newborn. Therefore, the statement “Colostrum is recommended for new born as it is rich in antigens” is false.

Chikungunya :
Chikungunya is a viral disease that spreads through the Aedes aegypti mosquito. Therefore, the statement “Chikungunya is caused by Gram (-) bacterium” is false.

Virus free plants :
Virus free plants can be obtained from an infected plant by apical meristem culture via tissue culture techniques. Therefore, this statement “Tissue culture is useful in obtaining virus free plants” is true.

Beer :
Wine is produced from fermented grape juice, whereas beer is produced from malted grains (mainly barley). Wine and beer are prepared without distillation. Therefore, the statement “Beer is obtained by distillation of fermented grape juice” is false.
