Task: Answer the multiple-choice question.
Query: Which compound exhibits a -9.420% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) COc1c(/C=N/NC(=O)[C@H]2C[C@@H]2c2ccccc2)c(CCN(C)C(C)=O)cc2c1OCO2
b) CCC(C)[C@@H](C(=O)Nc1ccc(OC)c(OC)c1)N1Cc2ccccc2C1=O
Answer: b. CCC(C)[C@@H](C(=O)Nc1ccc(OC)c(OC)c1)N1Cc2ccccc2C1=O
