Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.958\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CN(C)Cc1cc(C(C)(C)C)c(O)c(C(C)(C)C)c1
(b) CCCCN(CCCC)S(=O)(=O)c1ccc(C(=O)Nc2nnc(COC)o2)cc1
(c) CC(C)=CC(=O)OCC(=O)Nc1ccccc1Cl
(d) Cc1occc1-c1nnc(SCC(=O)N(C)CCC#N)n1N
(e) COc1ccccc1NC(=O)Nc1ccc(-n2ccc(C(F)(F)F)n2)cc1
Answer: b. CCCCN(CCCC)S(=O)(=O)c1ccc(C(=O)Nc2nnc(COC)o2)cc1
