Task: Answer the multiple choice question.
Query: Which drug has a 12.503\% 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 COc1ccccc1CNCc1cccs1.Cl
b CCOc1ccc(-n2c(SCc3ccc(C(=O)OC)o3)nc3c(c2=O)SCC3)cc1
c Cc1ccc(NC(=O)COC(=O)CCc2nc3ccccc3c(=O)[nH]2)cc1Cl
d O=C(NCc1ccccc1)C1CCCN1C(=O)Nc1ccccc1[N+](=O)[O-]
e CN1CCc2c(sc(NC(=O)Cc3ccc(F)cc3)c2C(N)=O)C1.Cl
Answer: d. O=C(NCc1ccccc1)C1CCCN1C(=O)Nc1ccccc1[N+](=O)[O-]
