Task: Answer the multiple-choice question.
Question: Which drug has a 19.658\% 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 other words.
Options:
[a] COc1ccc(-n2nc(C(=O)Nc3ccc4c(c3)OCO4)c3ccccc3c2=O)c(OC)c1
[b] CCOc1ccc(Nc2nc(Cc3nnc(SCC(=O)NCc4ccco4)n3CC)cs2)cc1
[c] CN(Cc1c[nH]c2ccccc12)C1CCCCC1
[d] CC(=O)C1=C(O)C(=O)N(CCc2c[nH]c3ccccc23)C1c1ccc(C)cc1
Answer: d. CC(=O)C1=C(O)C(=O)N(CCc2c[nH]c3ccccc23)C1c1ccc(C)cc1
