Problem statement: Answer the multiple choice question.
Query: Which drug has a 15.628\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(CN(c1ccc(Cl)cc1)S(=O)(=O)c1ccc(Cl)c([N+](=O)[O-])c1)NCCc1ccc(F)cc1
(b) CC(=O)c1c[nH]c(C(=O)NCc2ccccc2Cl)c1
(c) O=C(N[C@@H](Cc1ccccc1)C(=O)O)c1ccncc1.O=C(O)C(F)(F)F
(d) Cn1cc(C(=O)c2cccc(Cl)c2Cl)cc1C(=O)O
Answer: b. CC(=O)c1c[nH]c(C(=O)NCc2ccccc2Cl)c1
