The correct answer is (a) Cotton.
The Pink Revolution is a term used to describe the development of genetically modified cotton varieties that are resistant to the pink bollworm. The pink bollworm is a major pest of cotton, and the development of resistant varieties has had a significant impact on the cotton industry.
The pink bollworm is a moth that attacks cotton bolls, or the fruit of the cotton plant. The larvae of the pink bollworm feed on the cotton fibers, causing significant damage to the crop. The pink bollworm is a major pest of cotton in many parts of the world, including the United States, China, and India.
The development of genetically modified cotton varieties that are resistant to the pink bollworm has been a major breakthrough in the fight against this pest. These varieties have been engineered to produce a protein that is toxic to the pink bollworm. When the larvae of the pink bollworm feed on these varieties, they ingest the toxin and die.
The development of genetically modified cotton varieties that are resistant to the pink bollworm has had a significant impact on the cotton industry. These varieties have allowed farmers to reduce the use of pesticides, which has saved them money and reduced the environmental impact of cotton production. In addition, these varieties have increased yields, which has benefited farmers and consumers alike.
The Pink Revolution is a significant example of how biotechnology can be used to improve agriculture and protect the environment.
