Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 4.451\% 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: Cc1cccc(C)c1NC(=O)CN(C)C(=O)CCC(=O)c1ccccc1
b: NC(=O)[C@@H]1CC2(CC(c3cccc(NC(=O)CC(c4ccccc4)c4ccccc4)c3)=NO2)CN1C(=O)COc1ccc(Cl)cc1
c: COC(=O)C1=C(C(=O)OC)[C@@H]2N(C)c3ccc(OC)cc3[C@@]23C[C@@H](C(=O)OC)N(C(=O)c2ccc(Br)cc2)C3=N1
Answer: c. COC(=O)C1=C(C(=O)OC)[C@@H]2N(C)c3ccc(OC)cc3[C@@]23C[C@@H](C(=O)OC)N(C(=O)c2ccc(Br)cc2)C3=N1
