Task: Answer the multiple choice question.
Question: Which compound has a 15.196\% 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 other words.
Options:
a CCOC(=O)NC(=O)/C(C#N)=C/c1ccc(N(C)C)cc1
b COc1cccc(-c2nn(C)c3sc(C(=O)NCc4ccccn4)cc23)c1
c Cn1c(SCC(=O)N/N=C/C=C\c2ccco2)nc2ccccc21
d O=C(NN1C(=O)c2ccccc2NC1c1ccccn1)c1ccc([N+](=O)[O-])cc1
e Cc1ccc(Oc2cc([N+](=O)[O-])cc3c2C(=O)Nc2ccccc2O3)cc1
Answer: a. CCOC(=O)NC(=O)/C(C#N)=C/c1ccc(N(C)C)cc1
