Task: Answer the multiple-choice question.
Question: Which drug exhibits a 20.773\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccc(S(=O)(=O)Nc2cccc(C)n2)c2ccccc12
[b] CCN1CCc2[nH]c3ccccc3c2C1
[c] COc1ccc(NC(=O)COC(=O)CCCOc2ccc(Cl)cc2Cl)cc1Cl
[d] O=c1ncn(-c2ccc(F)cc2)c2ncccc12
Answer: c. COc1ccc(NC(=O)COC(=O)CCCOc2ccc(Cl)cc2Cl)cc1Cl
