Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -26.611% hERG inhibition at a concentration of 10uM?
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(O)CCCCCNC(=O)c1ccc(Br)cc1
b: Cc1ccccc1C(=O)O
c: CCN1CCN(C(=S)Nc2ccc([N+](=O)[O-])cc2)CC1
d: COC(=O)C(O)(CC(=O)Nc1ccc(OC)cc1)C(F)(F)F
e: O=[N+]([O-])c1cccc(-c2ccc(C(=S)N3CCOCC3)o2)c1
Answer: c. CCN1CCN(C(=S)Nc2ccc([N+](=O)[O-])cc2)CC1
