Task: Answer the multiple choice question.
Question: Which drug has a -4.364\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCCOC(=O)c1c(NC(=O)/C=C/c2cnn(C)c2C)sc(C(=O)OCC)c1C
b. CCOc1ccc(-c2ccc(SCC(=O)N3CCOCC3)nn2)cc1
c. CC1(C)CC(=O)C(C2C3=C(CC(C)(C)CC3=O)OC3=C2C(=O)CC(C)(C)C3)=C(O)C1
Answer: b. CCOc1ccc(-c2ccc(SCC(=O)N3CCOCC3)nn2)cc1
