Task: Answer the multiple choice question.
Query: Which drug has a 5.450\% 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 Cc1cc(CNC(=O)c2cccc([N+](=O)[O-])c2)c2ccccc2n1
b CCCCNc1ccc(C(CC(N)=O)NC(=O)Cc2cccc3ccccc23)cc1[N+](=O)[O-]
c O=c1c2c(-c3ccco3)csc2nc(SCc2cn3cccnc3n2)n1-c1ccccc1
d CCCn1c(N)c(N(CCOC)C(=O)c2ccc([N+](=O)[O-])cc2Cl)c(=O)[nH]c1=O
e Cc1onc(-c2ccccc2)c1C(=O)c1c[nH]c(C(=O)NCc2ccncc2)c1
Answer: a. Cc1cc(CNC(=O)c2cccc([N+](=O)[O-])c2)c2ccccc2n1
