Task: Answer the multiple choice question.
Question: Which compound has a -8.417% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=c1[nH]c(Cc2cccs2)nc2scc(-c3ccc(Cl)cc3)c12
b: O=C(c1ccncc1)N1N=C(C2CCCCC2)CC1(O)C(F)(F)F
Answer: a. O=c1[nH]c(Cc2cccs2)nc2scc(-c3ccc(Cl)cc3)c12
