Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.434\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCOc1[nH]n(-c2ccccc2)c(=O)c1C=NCc1cccnc1
[b] O=C(O)c1ccc(-n2nncc2-c2ccccc2)cc1
[c] COC(=O)C1CC(=O)N(CCc2c[nH]c3ccccc23)C1
[d] COc1ccc(N(CC(=O)NC2CC3CCC2C3)S(=O)(=O)c2ccccc2)cc1OC
Answer: c. COC(=O)C1CC(=O)N(CCc2c[nH]c3ccccc23)C1
