Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.826\% 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, d, or e without using any other words.
Options:
[a] O=C(O)c1ccc(CSc2nnc(-c3ccco3)o2)cc1
[b] CC(=O)c1cccc(NC(=O)CCNS(=O)(=O)c2cccc3nsnc23)c1
[c] CCN(CC(=O)NC)S(=O)(=O)c1ccc(C)cc1
[d] Cc1cc(N2CCC(C)CC2)n2ncc(-c3ccccc3)c2n1
[e] Cc1cc(/C=N\NC(=O)CC(=O)NC2CCCCC2)c(C)n1-c1ccc(Cl)cc1
Answer: d. Cc1cc(N2CCC(C)CC2)n2ncc(-c3ccccc3)c2n1
