Task: Answer the multiple choice question.
Query: Which compound has a 21.135% 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, or c without using any additional words.
Options:
[a] CN1C(=O)CC(N2CCN(c3ccccc3)CC2)C1=O
[b] C/C(Cl)=C/Cn1c(SCC(C)C)nc2c1c(=O)[nH]c(=O)n2C
[c] Cc1cc(=O)cc(C)n1-c1ccc2c(c1)nc(C)n2-c1ccccc1
Answer: a. CN1C(=O)CC(N2CCN(c3ccccc3)CC2)C1=O
