Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.248\% 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] O=C(CCSc1nnc(-c2ccncc2)o1)Nc1ccccc1Cl
[b] O=C(CN1CCOCC1)Nc1nc2cc([N+](=O)[O-])ccc2s1
[c] Cc1ccc(N=c2c([N+](=O)[O-])nn(-c3ccc4c(c3)OCCO4)n2O)c(Cl)c1
[d] COc1ccc(OC)c(NC(=S)NCc2ccccc2OC)c1
[e] O=C(Nc1nc(-c2cccnc2)cs1)c1ccccc1F
Answer: b. O=C(CN1CCOCC1)Nc1nc2cc([N+](=O)[O-])ccc2s1
