Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 8.180\% 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. O=C1CC(c2ccco2)CC(O)=C1C=NCCN1CCN(C(=O)Nc2ccc(Cl)cc2)CC1
b. COC(=O)c1ccccc1NC(=O)CSc1nnc(-c2cccc(NC(C)=O)c2)n1C
c. NC(=NCCc1ccccc1)NS(=O)(=O)c1ccc(F)cc1
Answer: c. NC(=NCCc1ccccc1)NS(=O)(=O)c1ccc(F)cc1
