Problem statement: Answer the multiple-choice question.
Query: Which compound has a 15.254\% 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 COc1ccc(/C=N/NC(=O)c2c(-c3ccccc3)noc2C)cc1
b O=C(Cn1cnc([N+](=O)[O-])n1)N/N=C/c1cc(Cl)ccc1O
c CCc1ccc2[nH]c(=O)c(CN(Cc3ccccc3OC)Cc3nnnn3Cc3ccco3)cc2c1
d C=C(C)CN=C1SC(C(=O)Nc2sc3c(c2C(=O)OC)CCC3)C(N)=C1C(N)=O
e CN1C(=O)C2(C(C#N)=C(N)N(c3cc(Cl)cc(Cl)c3)C3=C2C(=O)CCC3)c2ccccc21
Answer: b. O=C(Cn1cnc([N+](=O)[O-])n1)N/N=C/c1cc(Cl)ccc1O
