Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.166\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COC(=O)c1c(NC(=O)CSc2nnnn2C)sc(C)c1C
b: O=C(NCCc1ccc(Cl)cc1)C1CCCN1C(=O)Nc1ccc(F)cc1
c: Cc1cccnc1NC(=O)Nc1ccccc1
Answer: b. O=C(NCCc1ccc(Cl)cc1)C1CCCN1C(=O)Nc1ccc(F)cc1
