Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.190\% 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 additional words.
Options:
a: COc1ccc(CN(C)C(=S)NCCc2ccccc2)c(OC)c1OC
b: CCN(c1cc(C)cc(C)c1)S(=O)(=O)c1nnc(NC(=O)C(C)C)s1
c: CCOC(=O)C1CCCN(C(=O)c2cccc(S(=O)(=O)N3CCOCC3)c2)C1
Answer: a. COc1ccc(CN(C)C(=S)NCCc2ccccc2)c(OC)c1OC
