Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.925\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOC(=O)C1CCN(C(=O)/C(C)=C\c2ccccc2)CC1
b: CCOC(=O)c1c(C)[nH]c(=S)c(C#N)c1-c1ccc(OC)cc1
c: O=[N+]([O-])c1ccc2nccn2c1
d: O=C(COC(=O)/C=C/c1ccco1)NCCc1ccccc1
Answer: a. CCOC(=O)C1CCN(C(=O)/C(C)=C\c2ccccc2)CC1
