Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.820\% 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 other words.
Options:
[a] O=C(CSc1nc2c(cnn2-c2ccccc2)c(=O)[nH]1)N1CCOCC1
[b] CCNC(=O)C1CC(=O)N(c2ccc(Br)cc2)C1
[c] COc1cc(C)c(C(C)C)cc1S(=O)(=O)n1cnc(C)c1
[d] O=[N+]([O-])c1cnc2nc(-c3ccncc3)nn2c1[O-].[Na+]
[e] O=C1CC(c2cccs2)CC(O)=C1C=NCCN1CCNCC1
Answer: d. O=[N+]([O-])c1cnc2nc(-c3ccncc3)nn2c1[O-].[Na+]
