Problem statement: Answer the multiple choice question.
Query: Which drug has a -4.270% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) Nc1ccc(-c2nnnn2-c2ccc(N)cc2)cc1
b) O=C(NNc1ccc([N+](=O)[O-])cc1)c1ccco1
c) Cc1cccc(N(C(=O)c2nsc(Cl)c2Cl)C(C(=O)NC2CCCC2)c2ccc(O)cc2)c1C
d) Cc1sc2nc(SCC(=O)NCc3ccco3)n(C)c(=O)c2c1C
Answer: b. O=C(NNc1ccc([N+](=O)[O-])cc1)c1ccco1
