Task: Answer the multiple-choice question.
Question: Which drug exhibits a -6.775\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccc(OCCCC(=O)OCC(=O)Nc2sccc2C(N)=O)cc1
b: CC(c1nnc(Sc2nnnn2-c2ccccc2)n1-c1ccc(F)cc1)N(C)C
Answer: a. COc1ccc(OCCCC(=O)OCC(=O)Nc2sccc2C(N)=O)cc1
