Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 15.108\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COc1ccc(/C=N/N=C/c2ccc(OC)cc2)cc1
b. O=C(O)c1sccc1S(=O)(=O)N1CCOCC1
c. CCCn1c(=N)n(CC(O)COc2cccc(C)c2)c2ccccc21.Cl
Answer: b. O=C(O)c1sccc1S(=O)(=O)N1CCOCC1
