Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.996% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccnc(Oc2ccc(Cl)cc2)c1C#N
b CC1(C)CC(=O)C(N=Nc2cccc([N+](=O)[O-])c2)=C(O)C1
c CCOc1ccc(OCC)c(NC(=O)CSCCc2ccccn2)c1
d Cc1ccc2cc3c(NS(=O)(=O)c4cccc5nonc45)nn(CC(C)C)c3nc2c1
Answer: a. COc1ccnc(Oc2ccc(Cl)cc2)c1C#N
