Task: Answer the multiple-choice question.
Question: Which drug exhibits a -18.867% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC1(C)C/C(=N\O)C(C(O)c2cccc([N+](=O)[O-])c2)C(C)(C)N1
b COc1ccc(-n2c(SCC#N)nnc2-c2cccnc2)cc1
c O=C(CN1CCC(c2nc3ccccc3s2)CC1)NCc1cccs1
d O=C(c1cnc2ccccn2c1=O)N1CCc2ccccc21
e CCC(C)NC(=O)CSc1nc2ccsc2c(=O)n1NC(=O)c1ccccc1
Answer: d. O=C(c1cnc2ccccn2c1=O)N1CCc2ccccc21
