Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.549\% 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: COc1cc2c(cc1OC)CN(c1ccc([N+](=O)[O-])c(C(F)(F)F)c1)CC2
b: COc1ccc(CCNC(=O)CNCCc2ccc(F)cc2)cc1.O=C(O)C(=O)O
c: CCOC(=O)NC(=O)c1cn(Nc2ccccc2C(F)(F)F)c(=O)[nH]c1=O
Answer: c. CCOC(=O)NC(=O)c1cn(Nc2ccccc2C(F)(F)F)c(=O)[nH]c1=O
