Task: Answer the multiple choice question.
Question: Which compound has a 9.426\% 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) CCOC(=O)C1CN(S(=O)(=O)c2ccccc2)c2cc(S(=O)(=O)CC)ccc2O1
(b) CC1CC(C)CN(Cc2nc(N)nc(Nc3ccc4ccccc4c3)n2)C1
(c) O=S(=O)(Nc1ccc(Cl)c(C(F)(F)F)c1)c1cnc[nH]1
(d) CCCc1nn(C)c(C(N)=O)c1[N+](=O)[O-]
Answer: c. O=S(=O)(Nc1ccc(Cl)c(C(F)(F)F)c1)c1cnc[nH]1
