Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 7.167\% 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 additional words.
Options:
a COc1cc(O)c(C(CC(=O)N2CCCCC2)c2ccc3c(c2)OCO3)c(OC)c1
b COc1cc(CN2CCN(c3ccccc3C)CC2)cc([N+](=O)[O-])c1O
c CCOc1ccc(N2CC(C(=O)Nc3ncccc3C)CC2=O)cc1
d CN(Cc1nc(-c2cccnc2)no1)S(=O)(=O)c1ccc(Br)cc1
e CCn1nc(C(=O)OC(C(=O)c2c[nH]c3ccccc23)c2ccccc2)c2ccccc2c1=O
Answer: b. COc1cc(CN2CCN(c3ccccc3C)CC2)cc([N+](=O)[O-])c1O
