Task: Answer the MCQ question.
Query: Which compound exhibits a -18.434% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C1C(Cl)=C(NCC2CCCO2)C(=O)N1c1cccc(Cl)c1Cl
(b) COC(=O)CCC(=O)OC1(C)C(=O)C2=CN(CCN3CCOCC3)C(c3ccc(OC)cc3)=CC2=C(Br)C1=O
(c) CCCCN(CCCC)c1ccc(C(=O)c2ccccc2C(=O)O)c(O)c1
Answer: a. O=C1C(Cl)=C(NCC2CCCO2)C(=O)N1c1cccc(Cl)c1Cl
