Task: Answer the multiple choice question.
Question: Which drug has a -12.882\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] Cc1ccc(S(=O)(=O)N2CCN(C(=O)c3ccccc3)CC2)cc1
[b] O=C(NCc1ccccn1)Nc1ccc(F)c(Cl)c1
Answer: b. O=C(NCc1ccccn1)Nc1ccc(F)c(Cl)c1
