Task: Answer the multiple-choice question.
Question: Which compound has a 18.366\% 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: O=C(CSc1nnc(NC(=O)c2ccco2)s1)Nc1ccccc1Cl
b: COc1ccccc1N(C(=O)NCc1ccccc1)C1=NCC(C)S1
c: CSc1nc(N)nc(N(C)C)n1
Answer: a. O=C(CSc1nnc(NC(=O)c2ccco2)s1)Nc1ccccc1Cl
