Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.526\% 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: c1ccc(C[C@H]2CNCCN2CCCCC2CCCCC2)cc1
b: COc1ccccc1NC(=O)c1ccc2c(O)c(S(=O)(=O)c3ccccc3)c(=O)[nH]c2c1
c: Cc1[nH]n(-c2c(Cl)cc(Cl)cc2Cl)c(=O)c1C=Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
d: O=C1c2ccccc2C(=O)N1CCN1CCc2ccccc21
e: COc1ccc(NC(=O)N2CCC3(CC2)OCCO3)cc1OC
Answer: d. O=C1c2ccccc2C(=O)N1CCN1CCc2ccccc21
