Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.739\% 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 COc1cnn(-c2cc(Oc3ccc(C)cc3)ncn2)c(=O)c1Cl
b Cc1nn(C2CCOC(C)(C)C2)c2c1C(c1ccc(OC(C)C)cc1)SCC(=O)N2
c Cn1cc(/C=C2/SC(=O)N(CC(=O)Nc3ccc4c(c3)OCO4)C2=O)c2ccccc21
d CCN(CCCNc1ncnc2nc[nH]c12)c1cccc(C)c1
e CN1C(=O)CC(N2CCN(c3ccccc3)CC2)C1=O
Answer: e. CN1C(=O)CC(N2CCN(c3ccccc3)CC2)C1=O
