Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.803\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOC(=O)c1ccc2c(c1)C1C=CCC1C(C(=O)O)N2
b: O=c1c2ccccc2nc(-c2ccccc2)n1Cc1ccco1
c: Cc1ccccc1C(=O)OC1OC(=O)C(Cl)=C1Nc1ccccc1
d: Cc1cccc(/C=N/N(CCO)C2=NS(=O)(=O)c3ccccc32)c1
e: O=C1SCCC1NS(=O)(=O)c1ccccc1[N+](=O)[O-]
Answer: b. O=c1c2ccccc2nc(-c2ccccc2)n1Cc1ccco1
