Task: Answer the multiple choice question.
Question: Which compound exhibits a -5.119\% 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: O=C(CSc1nc(SCC(=O)NCc2ccccc2)n(-c2ccccc2)n1)NCc1ccccc1
b: CCN1C(=O)C(CC(=O)NC)N(NC(=O)c2ccccc2)C1=S
c: CCOC(=O)c1ccc(NC(=O)COC)cc1
Answer: b. CCN1C(=O)C(CC(=O)NC)N(NC(=O)c2ccccc2)C1=S
