Task: Answer the multiple choice question.
Question: Which compound has a 12.854\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=C(Nc1ccccc1-c1ccccc1)C1CCCN(c2ncccn2)C1
b) COCCCn1c(=O)c2ccccc2n(Cc2cccc(C)c2)c1=O
c) CCCc1cc(=O)[nH]c(SCC(=O)Nc2ccc(Cl)c(S(=O)(=O)N3CCOCC3)c2)n1
d) O=C(c1ccco1)N(Cc1cccc(F)c1)C1CCS(=O)(=O)C1
Answer: b. COCCCn1c(=O)c2ccccc2n(Cc2cccc(C)c2)c1=O
