Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.057% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(Cn1c(C(F)(F)F)nc2ccccc21)Oc1cccc(C(F)(F)F)c1
[b] CC(=O)c1c[nH]c(C(=O)NC2CCCCCC2)c1
Answer: a. O=C(Cn1c(C(F)(F)F)nc2ccccc21)Oc1cccc(C(F)(F)F)c1
