Task: Answer the multiple choice question.
Question: Which compound exhibits a -12.740% 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 additional words.
Options:
[a] NC(=S)N/N=C/c1coc2ccc(Cl)cc2c1=O
[b] O=C(NCC1(N2CCCCC2)CCCCC1)c1cc([N+](=O)[O-])ccc1Cl
Answer: b. O=C(NCC1(N2CCCCC2)CCCCC1)c1cc([N+](=O)[O-])ccc1Cl
