1. Biofortification involves the genetic alteration of plants to increase their resistance to pests.
This statement is incorrect. Biofortification refers to the process of enhancing the nutritional value of food crops by increasing the content of essential vitamins and minerals. It does not specifically aim to increase pest resistance. Pest resistance is typically achieved through other agricultural practices or genetic modifications, but it is not the primary focus of biofortification.
2. Golden Rice has been biofortified to address vitamin A deficiency.
This statement is correct. Golden Rice is a well-known example of a biofortified crop. It has been genetically engineered to produce beta-carotene, a precursor of vitamin A, to help address vitamin A deficiency, particularly in regions where this deficiency is prevalent and causes significant health problems.
3. Biofortified crops are primarily aimed at combating macronutrient deficiencies.
This statement is incorrect. The primary aim of biofortified crops is to combat micronutrient deficiencies, such as deficiencies in vitamins and minerals like vitamin A, iron, and zinc. Macronutrients include proteins, fats, and carbohydrates, which are not the main focus of biofortification efforts.
Therefore, the correct answer is Option D: 2 Only.
