Task: Answer the multiple choice question.
Question: Which compound has a 2.646% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)/C=C/C(=O)Nc1ccccc1-c1ccccc1NC(=O)/C=C/C(=O)OCC
b: CCOC(=O)c1ccc(CN(Cc2ccccc2)S(=O)(=O)c2cccc([N+](=O)[O-])c2)cc1
c: COc1ccc(C2=NN(CCC(=O)NC3CCCCCC3)C(=O)CC2)cc1
d: COc1cc(C=C2C(=O)NC(=O)NC2=O)cc(OC)c1OC
Answer: a. CCOC(=O)/C=C/C(=O)Nc1ccccc1-c1ccccc1NC(=O)/C=C/C(=O)OCC
