Task: Answer the multiple choice question.
Question: Which compound exhibits a -10.424% 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. CC1(C)CC(=O)C(CC2=C(O)CC(C)(C)CC2=O)=C(O)C1
b. O=C(CSc1ccccc1)Nc1ccc2c(c1)OCCO2
Answer: b. O=C(CSc1ccccc1)Nc1ccc2c(c1)OCCO2
