Task: Answer the multiple choice question.
Query: Which drug has a -4.878% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(C)(C)c1ccc(OCC(=O)NNC(=O)CCc2ccccc2)cc1
b: O=C(COC(=O)CCCNC(=O)c1ccc(Cl)cc1)Nc1ccc(Br)cc1
Answer: a. CC(C)(C)c1ccc(OCC(=O)NNC(=O)CCc2ccccc2)cc1
