Task: Answer the multiple choice question.
Question: Which drug has a 1.761\% 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 other words.
Options:
(a) CN(C)S(=O)(=O)c1cc(C(=O)NCC2CCCO2)c(Cl)cc1Cl
(b) Nc1ccccc1C(=O)NNc1ncc(C(F)(F)F)cc1Cl
(c) CNCCCOc1cccc(OC(C)C)c1.O=C(O)C(=O)O
(d) C=CCn1c(SCC(=O)NC(=O)c2cccc([N+](=O)[O-])c2)nnc1-c1ccccc1
Answer: b. Nc1ccccc1C(=O)NNc1ncc(C(F)(F)F)cc1Cl
