The Correct Option is A

Solution and Explanation

Answer (a) Streptococcus
(i) Streptococcus is employed in the manufacturing of streptokinase, a clot buster used to remove clots from the blood vessels of heart attack victims.
(ii) Lactobacillus is employed in the curdling process because it transforms lactose into lactic acid. This lactic acid causes the milk protein casein to coagulate, resulting in the creation of curd.
(iii)The unicellular yeast Saccharomyces cerevisiae is known to generate the enzyme zymase, which combines with glucose to make ethanol and carbon dioxide. It is frequently used in the bread and alcoholic beverage industries.
