Solution

The correct option is B Human insulin
Humulin R U-100 is a polypeptide hormone structurally identical to human insulin synthesized through rDNA technology in a special non-disease-producing laboratory strain of Escherichia coli bacteria. Eli Lilly marketed the first such insulin, Humulin, in 1982. Therefore, the correct answer is option B.
