Task: Answer the multiple-choice question.
Question: Which drug exhibits a -21.236% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] C#Cc1ccc([C@@H]2C=C(C(=O)N3CCN(Cc4ccc5c(c4)OCO5)CC3)O[C@H](OCCCCO)C2)cc1
[b] O=C(CSCC(=O)Nc1cccc([N+](=O)[O-])c1)Nc1ccccc1
[c] CCOC(=O)c1ccc2c(c1)n(CC)c(/C=C/N(C)c1ccccc1)[n+]2CC.[I-]
Answer: b. O=C(CSCC(=O)Nc1cccc([N+](=O)[O-])c1)Nc1ccccc1
