Task: Answer the multiple choice question.
Question: Which drug has a 13.048\% 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: O=C(Nc1ccccc1)C1=C[C@@H](c2csc3ccccc23)C[C@@H](OCc2ccc(CO)cc2)O1
b: CN1CCC(N(C)C(=O)CCc2nc3ccccc3c(=O)[nH]2)CC1
c: COc1ccc(C(=O)N/N=C\c2ccc(OC)c(COc3ccccc3Br)c2)c(OC)c1
d: Cc1ccc(-c2nc(CN(C)C3CCOCC3)c(C)o2)s1
e: COc1ccc2[nH]c3c(Cl)ncnc3c2c1
Answer: e. COc1ccc2[nH]c3c(Cl)ncnc3c2c1
