Task: Answer the multiple-choice question.
Query: Which drug exhibits a -10.318\% human ether-à-go-go related gene (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(CCNC(=O)CSc2nc(O)c(CC(C)C)c(=O)[nH]2)cc1OC
[b] O=C(COC(=O)CNS(=O)(=O)c1ccc(F)c(F)c1F)Nc1ccc(OC(F)F)cc1
Answer: b. O=C(COC(=O)CNS(=O)(=O)c1ccc(F)c(F)c1F)Nc1ccc(OC(F)F)cc1
