Task: Answer the multiple-choice question.
Query: Which drug has a -2.012\% 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=CN1CCN(C(=O)c2ccccc2Cl)CC1
[b] Cc1cccc(NC(=O)CSCC(=O)Nc2cccc3ncccc23)c1
[c] O=C(c1ccccc1Cl)N1CCN(Cc2ccc3c(c2)OCO3)CC1
[d] CSc1ncc(Cl)c(C(=O)O)n1
[e] O=C(CSc1ccccn1)Nc1ccc(Cl)c([N+](=O)[O-])c1
Answer: c. O=C(c1ccccc1Cl)N1CCN(Cc2ccc3c(c2)OCO3)CC1
