Problem statement: Answer the multiple choice question.
Query: Which drug has a -12.874% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC(=O)N1CCc2cc(Br)cc(S(=O)(=O)N3CCCCCC3)c21
[b] CCc1ccc(OCC(=O)NCCOc2ccccc2)cc1
[c] O=C(c1ccc(Cl)cc1[N+](=O)[O-])N(Cc1ccccc1)Cc1ccccc1
[d] CCN(C(=O)N(CC)c1ccccc1)c1ccccc1
Answer: c. O=C(c1ccc(Cl)cc1[N+](=O)[O-])N(Cc1ccccc1)Cc1ccccc1
