Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.983% 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: COc1ccc([N+](=O)[O-])cc1NC(C)C
b: COc1cc2c(cc1OC)C(=O)N(C)CC2
c: CCN1CCN(C(=O)C2=CC(c3ccc(C)cc3)=NS(=O)(=O)N2C)CC1
d: COc1cc(/C=C2/SC(=Nc3ccc(O)cc3)NC2=O)ccc1O
e: O=C(NCCCCCCCCCNC(=O)C(F)(F)F)C(F)(F)F
Answer: a. COc1ccc([N+](=O)[O-])cc1NC(C)C
