Task: Answer the multiple choice question.
Query: Which compound has a 13.486\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(NCc1cccnc1)c1cccc(C(F)(F)F)c1
b) Cc1ccc(N2C(=O)c3ccc(C(=O)NCCN4CCOCC4)cc3C2=O)cc1
Answer: a. O=C(NCc1cccnc1)c1cccc(C(F)(F)F)c1
