Task: Answer the multiple choice question.
Question: Which drug has a 13.006\% 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.

b: Cc1ccc(C)c2c1[nH]c1ccc([N+](=O)[O-])cc12
c: CCc1nnc(NC(=O)c2ccc(-c3cccc(C(F)(F)F)c3)o2)s1
d: Cc1ccnc(SCC(=O)Nc2oc(-c3ccccc3)c(-c3ccccc3)c2C#N)n1
e: CCOC(=O)CCC(=O)Nc1ccc(S(=O)(=O)N2CCc3ccccc32)cc1
Answer: b. Cc1ccc(C)c2c1[nH]c1ccc([N+](=O)[O-])cc12
