Problem statement: Answer the multiple choice question.
Query: Which compound has a 1.786\% 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(Nc1nnc(CSCc2ccc(F)cc2)s1)c1cccc([N+](=O)[O-])c1
b. COc1cc(S(=O)(=O)NC2CCSc3ccccc32)ccc1NC(C)=O
c. CCCCn1c(N)c(N(CCOC)C(=O)c2cnc(C)cn2)c(=O)[nH]c1=O
Answer: c. CCCCn1c(N)c(N(CCOC)C(=O)c2cnc(C)cn2)c(=O)[nH]c1=O
