Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.796\% human ether-à-go-go related gene (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: C=CCN(CC=C)c1nc2ccccc2nc1C(C#N)C(=O)OCCOC
b: Cl.Clc1ccc(Cn2c(CN3CCCC3)nc3ccccc32)cc1
c: CCN(C(=O)c1ccc2c(=O)n3c(nc2c1)CCCCC3)c1ccccc1C
d: O=C(CSCc1ccccc1Cl)Nc1c[nH]c(=O)[nH]c1=O
Answer: a. C=CCN(CC=C)c1nc2ccccc2nc1C(C#N)C(=O)OCCOC
