Solution

The correct option is A Obtained in large unlimited quantities
Genetically modified bacteria are used to produce large amounts of proteins for industrial use. Generally, the bacteria are grown to a large volume before the gene encoding the protein is activated. The bacteria are then harvested and the desired protein purified from them. The high cost of extraction and purification has meant that only high-value products have been produced at an industrial scale. For example, E.coli is used to make genetically engineered insulin production.
So the correct answer is option B.
