Task: Answer the multiple-choice question.
Question: Which compound has a 4.936\% 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. COC(=O)C(CC(C)C)N1CCC(=O)c2ccccc2S1(=O)=O
b. COc1cccc(-n2c(Cc3cc(=O)[nH]c(=O)[nH]3)nnc2SCC(=O)N2CCCC2)c1
c. COc1ccc(OCc2cccc(C(=O)Nc3cc(C)on3)c2)cc1
d. O=C(c1cc(-c2cccnc2)nc2ccc(Cl)cc12)N1CCN(S(=O)(=O)c2cccs2)CC1
Answer: a. COC(=O)C(CC(C)C)N1CCC(=O)c2ccccc2S1(=O)=O
