Task: Answer the multiple-choice question.
Query: Which drug has a -2.804\% 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 additional words.
Options:
(a) COc1ccc(OC)c(N2C(=NC(=O)C3CCCCC3)SC3CS(=O)(=O)CC32)c1
(b) O=C(COc1ccccc1)Nc1ccc(-c2ccc(N3CCOCC3)nn2)cc1
(c) CC(C)CC(=O)N1CCN(S(C)(=O)=O)CC1
(d) COc1cc(C)nc(NS(=O)(=O)c2ccccc2Cl)n1
Answer: b. O=C(COc1ccccc1)Nc1ccc(-c2ccc(N3CCOCC3)nn2)cc1
