Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.393\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cc1ccc(/C=C2/NC(=O)N(Cc3ccc(Br)cc3)C2=O)o1
b COC(=O)c1c(N=CN(C)C)c(C#N)c2n1CCCC2
c CCOC(=O)C1=C2c3ccc4ccccc4c3CC(C)(C)N2C(=O)C1=O
d O=C(CN(Cc1ccccc1)S(=O)(=O)c1ccc2c(c1)OCCO2)N/N=C/c1ccc(F)cc1
Answer: c. CCOC(=O)C1=C2c3ccc4ccccc4c3CC(C)(C)N2C(=O)C1=O
