Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 15.996\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a S=C(Nc1ccccc1)Nc1nccs1
b COc1ccc(NC(=O)C2CC(c3ccccc3O)=NO2)cc1OC
c O=C(c1ccc2c(c1)OCO2)N1CCN(S(=O)(=O)c2ccc(Br)cc2Cl)CC1
Answer: a. S=C(Nc1ccccc1)Nc1nccs1
