Task: Answer the multiple-choice question.
Question: Which drug has a -10.974% 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: CC1COc2ccccc2N1C(=O)c1ccc(Cl)nc1
b: COc1ccccc1Oc1coc2c(CN(C)C)c(O)ccc2c1=O
c: COc1ccc(S(=O)(=O)NCC(=O)N(CC2CCCO2)C(C(=O)NC2CCCC2)C(C)C)cc1
d: COC(=O)/C=C1\SC(=NC(=O)c2ccc(C)cc2)NC1=O
Answer: b. COc1ccccc1Oc1coc2c(CN(C)C)c(O)ccc2c1=O
