Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 8.929\% 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. CCOC(=O)Cn1c(=O)oc2cc(S(=O)(=O)NCCc3ccc(C)cc3)ccc21
b. Cc1cccc(Cn2c(N3CCN(CCO)CC3)nc3c2c(=O)[nH]c(=O)n3C)c1
c. O=C(OCc1nnc(-c2ccccc2)o1)c1cc([N+](=O)[O-])ccc1Cl
Answer: c. O=C(OCc1nnc(-c2ccccc2)o1)c1cc([N+](=O)[O-])ccc1Cl
