Task: Answer the multiple-choice question.
Question: Which compound exhibits a 11.515\% 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(Nc1ccccc1F)c1cc(C(=O)Nc2ccccc2F)cc([N+](=O)[O-])c1
[b] COC(=O)C(CCSC)NC(=O)c1cn(-c2ccc(OC)cc2)c(=O)c2ccccc12
[c] Cc1ccccc1N1CCN(S(=O)(=O)N(C)C)CC1
[d] CC(=O)c1ccc(/C(C#N)=C/c2ccccc2)s1
Answer: a. O=C(Nc1ccccc1F)c1cc(C(=O)Nc2ccccc2F)cc([N+](=O)[O-])c1
