  • Spirulina a type of cyanobacteria is a perfect representation of SCP (single-cell protein). Vitamins B1 and B2, iron, manganese, carbohydrates, and approximately 60% protein are all found in dried spirulina.
  • Protein production by Methylophilus methylotrophus is extremely rapid. To see precisely how proficiently this bacterium functions, we can consider a cow weighing 250 Kg. One day, this cow can produce 200 grams of protein. Despite the fact that it takes up 3-10 Kg of cereal it delivers a measly 1 Kg of meat. Methylophilus methylotrophus, on the other hand, can make 25 tons of protein with just 250 grams. A and B are the best choices in light of the preceding information.
  • Golden rice is a variety of rice that is produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, rather than calcium. It is incorrect to say that common button mushrooms are a rich source of vitamin C; rather, they are a rich source of vitamin B. So, these are incorrect statements.


Hence, the correct answer is option 3.
