Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 31.862\% 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=c1sc2ccccc2n1CCOc1ccccc1
b CCOC(=O)/C(C#N)=C/c1ccc(OCC(=O)Nc2ccccc2)c(OC)c1
c CCCCc1ccc(NC(=O)N2CCNC(=O)C2CC(=O)Nc2ccsc2C(=O)OC)cc1
d COC(=O)c1cc(-c2c(C)oc3cc(O)ccc3c2=O)c(C)o1
e COC(=O)N/N=C/c1cc([N+](=O)[O-])cc(Br)c1O
Answer: e. COC(=O)N/N=C/c1cc([N+](=O)[O-])cc(Br)c1O
