Task: Answer the multiple-choice question.
Question: Which drug has a 7.696\% 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 additional words.
Options:
a: CC(C1CC2CCC1C2)N1CC(O)=C(c2nc3ccccc3[nH]2)C1=N
b: COCCN(CCOC)C(=O)COC(=O)c1cc([N+](=O)[O-])ccc1Cl
c: Cc1ccc(Sc2c([N+](=O)[O-])c(=O)n(C)c3ccccc23)cc1
d: CC1CCCC(C)N1/N=C/c1ccc(C#N)cc1
e: CCOC(=O)c1c(-c2ccc(-c3ccccc3)cc2)csc1NC(=O)C1C2CCC(O2)C1C(=O)O
Answer: a. CC(C1CC2CCC1C2)N1CC(O)=C(c2nc3ccccc3[nH]2)C1=N
