Task: Answer the multiple-choice question.
Query: Which compound exhibits a 3.693\% 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] C[N+](C)(CC#Cc1ccccc1)CC(=O)c1ccc(Cl)cc1
[b] Nc1nc(-c2cccc(Br)c2)cs1
[c] O=C(O)CC1S/C(=N\N=C2CCCCCCC2)N(c2ccccc2)C1=O
[d] Cl.O=[N+]([O-])c1cc(CN(CCO)CCO)ccc1O
[e] COc1ccc2[nH]c(=O)c(CN(C(=O)C3CCCO3)c3ccc(C)c(C)c3)cc2c1
Answer: d. Cl.O=[N+]([O-])c1cc(CN(CCO)CCO)ccc1O
