Task: Answer the multiple-choice question.
Question: Which compound exhibits a -8.255% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCc1c(C)nc2c(-c3ccccc3)c(C)nn2c1Nc1ccc(NC(C)=O)cc1
b: O=C(NCCCCc1ccccc1)Nc1cccc(F)c1
c: O=C(C1=C(O)C(=O)N(CC2CCCO2)C1c1cccc(Cl)c1)c1ccco1
d: N#C/C(=C\c1c(N2CCOCC2)nc2ccccn2c1=O)S(=O)(=O)c1ccccc1
Answer: b. O=C(NCCCCc1ccccc1)Nc1cccc(F)c1
