Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -14.921\% 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) O=C(c1ccc2c(c1)OCO2)N1CCCc2ccccc21
b) O=C(CC1CCCCC1)NCc1ccc(Cl)cc1
c) O=[N+]([O-])c1ccccc1O[C@@H]1O[C@H](CO)[C@H](O)[C@H](O)[C@H]1O
d) CN1CCN(S(=O)(=O)c2ccc(Nc3ccc(F)cc3)c([N+](=O)[O-])c2)CC1
e) O=C(NCc1ccccn1)C1(C(F)(F)F)C/C(=C\CCO)CCCO1
Answer: d. CN1CCN(S(=O)(=O)c2ccc(Nc3ccc(F)cc3)c([N+](=O)[O-])c2)CC1
