Task: Answer the multiple choice question.
Question: Which drug has a -13.281\% 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] CCCCN(C)CCNC(=O)c1ccc(Cn2c(=S)[nH]c3ccc(Br)cc3c2=O)cc1
[b] O=c1nc(SCc2cccc(C(F)(F)F)c2)nc2ccccn12
Answer: b. O=c1nc(SCc2cccc(C(F)(F)F)c2)nc2ccccn12
