Task: Answer the multiple choice question.
Question: Which drug has a -2.478\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CC(=O)c1cccc(NC(=O)c2oc(C)nc2C)c1
b: O=C(O)CCC(=O)NNC(=O)c1cccc(Br)c1
c: Cc1ccc(-c2csc(NC(=O)c3ccc(Br)cc3)c2C(=O)O)cc1
Answer: a. CC(=O)c1cccc(NC(=O)c2oc(C)nc2C)c1
