Task: Answer the multiple choice question.
Question: Which compound has a 12.845\% 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) CCCC(=O)N(Cc1cc(=O)[nH]c2ccccc12)c1ccc(OC)cc1
(b) COC(=O)c1ccc(C(=O)OC)c(NC(=S)N2CCCCC2)c1
(c) O=[N+]([O-])c1cccnc1Sc1ccc(Br)cc1
Answer: c. O=[N+]([O-])c1cccnc1Sc1ccc(Br)cc1
