Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.130\% 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=C(OCc1ccc(F)cc1Cl)c1ccccn1
b. COc1cccc(NC(=S)NNC(=O)c2c([N+](=O)[O-])c(C)nn2C)c1
c. COc1ccc(NC(=O)CCC(=O)c2cccs2)cc1S(=O)(=O)Nc1ccccc1Cl
Answer: a. O=C(OCc1ccc(F)cc1Cl)c1ccccn1
