Task: Answer the multiple-choice question.
Question: Which drug exhibits a 10.236\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] N#Cc1cc([N+](=O)[O-])cnc1NCC(O)CO
[b] CNS(=O)(=O)c1ccc(NC(=O)c2cc(-c3ccncc3)nc3ccc(Cl)cc23)cc1
[c] CC(C)OS(C)(=O)=O
[d] COc1ccc(-c2sc3cc4c(cc3c2C#CC2(O)CCCCC2)OCO4)cc1
Answer: c. CC(C)OS(C)(=O)=O
