Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.724\% 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=S(=O)(c1cccc(F)c1)N1CCN(C(=S)NCc2ccccc2)CC1
(b) CCn1nnnc1-c1ccc(OC)c(S(=O)(=O)Nc2ccc(S(N)(=O)=O)cc2)c1
(c) Nc1ccc(C(=O)N2N=C(c3ccc(F)cc3)CC2(O)C(F)(F)F)cc1
(d) CC(NC(N)=O)C(=O)Nc1ccc(Cl)c(S(=O)(=O)Nc2ccc(Br)cc2)c1
Answer: b. CCn1nnnc1-c1ccc(OC)c(S(=O)(=O)Nc2ccc(S(N)(=O)=O)cc2)c1
