Task: Answer the multiple choice question.
Query: Which compound has a 8.579\% 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 other words.
Options:
a: Cn1ccnc1SCC(=O)n1c2c(c3ccccc31)CCCC2
b: CCOC(=O)c1cc(NC(=O)/C=C\C(=O)O)ccc1Cl
c: C=CCN(c1ccccc1)S(=O)(=O)c1cccc2cccnc12
d: CCNC(=S)NS(=O)(=O)c1ccc(CC)cc1
Answer: b. CCOC(=O)c1cc(NC(=O)/C=C\C(=O)O)ccc1Cl
