Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 13.987\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(NCc1ccccn1)Nc1ccc(Cl)cc1
[b] O=C(Cn1cnc2c(cnn2-c2ccccc2)c1=O)OCc1ccccc1
[c] COc1ccc(Cn2cnc3c([N+](=O)[O-])c(C)c(C)cc32)cc1
[d] CCOC(=O)C(C)Sc1nnc(CNC(=O)c2ccc(OC)cc2)n1C1CCCCC1
[e] NC(=O)C1=C[C@@H](c2ccc(C(F)(F)F)cc2)C[C@@H](OCCCCO)O1
Answer: b. O=C(Cn1cnc2c(cnn2-c2ccccc2)c1=O)OCc1ccccc1
