Task: Answer the multiple choice question.
Question: Which compound has a -0.955\% 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: COc1cc(/C=N/NC(N)=O)ccc1OCC(=O)Nc1ccc(C)c(C)c1
b: O=[N+]([O-])c1ccc(C2=CSC3=NCCN23)cc1
c: Cc1ccnc(NC(=O)CCC(=O)N(CC(=O)NCCc2ccccc2)Cc2cccs2)c1
Answer: b. O=[N+]([O-])c1ccc(C2=CSC3=NCCN23)cc1
