Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.880% human ether-à-go-go related gene (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 COc1ccc(Nc2ncnc3ccc(Br)cc23)c(OC)c1
b O=c1[nH][nH]c(C(F)(F)F)c1C=NCc1ccc(Cl)cc1
Answer: b. O=c1[nH][nH]c(C(F)(F)F)c1C=NCc1ccc(Cl)cc1
