Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.943\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CC(=NCc1ccco1)c1c(O)n(C)c(=O)n(C)c1=O
b: O=C(Nc1nc(-c2ccccc2)cs1)c1ccc2c(=O)n3c(nc2c1)CCCCC3
c: COc1cc(S(=O)(=O)n2ccc(C)n2)ccc1Cl
Answer: c. COc1cc(S(=O)(=O)n2ccc(C)n2)ccc1Cl
