Task: Answer the multiple choice question.
Question: Which compound has a 16.038\% 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: O=C(NCCc1cnc[nH]1)Nc1cccc(C(F)(F)F)c1
b: O=C(C(Cl)Cl)N1CCN(Cc2ccc3c(c2)OCO3)CC1
Answer: a. O=C(NCCc1cnc[nH]1)Nc1cccc(C(F)(F)F)c1
