Task: Answer the multiple-choice question.
Question: Which compound has a -2.481% 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] O=C(Nc1cccc(C(F)(F)F)c1)c1cc2c(s1)-c1ccccc1OC2
[b] Cc1cccc(C(=O)Nc2ccc(N3CCN(S(C)(=O)=O)CC3)cc2)c1
Answer: a. O=C(Nc1cccc(C(F)(F)F)c1)c1cc2c(s1)-c1ccccc1OC2
