Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 15.685% 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: CC(=O)c1ccc(NC(=O)CO/N=C(\C)c2cccs2)cc1
b: Cc1nc(SCC(=O)NC(=O)NCc2ccccc2)nc(C)c1C
c: O=C1OCC(c2ccccc2)=C1c1ccccc1[N+](=O)[O-]
d: Cc1cc(C)nc(SCC(=O)Nc2ccc(S(=O)(=O)NC(C)(C)C)cc2)n1
e: Cc1cccc(C(=O)OCC(=O)Nc2sc3c(c2C#N)CCC3)c1
Answer: c. O=C1OCC(c2ccccc2)=C1c1ccccc1[N+](=O)[O-]
