Task: Answer the multiple choice question.
Question: Which drug has a -14.848% 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) CCCCOC(=O)C1=C(C)NC2=C(C(=O)CCC2)C1c1cc(OC)ccc1OC
(b) O=C(CSc1nnc(COc2ccccc2)o1)NC1CC2CCC1C2
Answer: a. CCCCOC(=O)C1=C(C)NC2=C(C(=O)CCC2)C1c1cc(OC)ccc1OC
