Task: Answer the multiple choice question.
Question: Which compound has a 20.288\% 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, c, or d without using any additional words.
Options:
a) NC1=NC(c2ccccc2Cl)n2c(nc3ccccc32)N1
b) COc1cc(OC)cc(C(=O)Nc2sc3c(c2C(N)=O)CCC3)c1
c) COc1cc(OC)cc(C(=O)Nc2ccc(C(=O)NCC3CCCO3)cc2)c1
d) CCN(Cc1ccccc1)C(=O)CSc1nncn1C
Answer: b. COc1cc(OC)cc(C(=O)Nc2sc3c(c2C(N)=O)CCC3)c1
