Task: Answer the multiple-choice question.
Question: Which compound has a 15.447\% 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, b, c, or d without using any additional words.
Options:
(a) O=C(Nc1ccccc1N1CCOCC1)C1CCN(S(=O)(=O)c2cccc(C(F)(F)F)c2)CC1
(b) O=C(CCN1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1)Nc1ccccc1F
(c) O=C(N/N=C/c1ccc[nH]1)c1cc2ccccc2cc1O
(d) COc1ccc(N=c2cc(-c3ccc(OC)cc3)oc3ccccc23)cc1
Answer: c. O=C(N/N=C/c1ccc[nH]1)c1cc2ccccc2cc1O
