Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.268\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) CCOC(=O)C1(Cc2ccccc2)CCCN(CCO)C1
b) Cc1ccc(OCCNC(=O)c2ccccc2OCc2c(C)noc2C)cc1
c) O=C(c1ccccc1Cc1ccccc1)N1CCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])CC1
d) CC(=O)c1cc(C(=O)Nc2ccc(C(=O)O)cc2)oc1C
e) O=C(NCc1ccccc1)C1CCN(c2nc(-c3ccccc3)nc3c2CCC3)CC1
Answer: e. O=C(NCc1ccccc1)C1CCN(c2nc(-c3ccccc3)nc3c2CCC3)CC1
