Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.721\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a Br.C/C(CC1CC(COCC(C)C)OC1=O)=N\Nc1nc(-c2ccccc2)cs1
b CCc1ccccc1N1C[C@@]23C=C[C@@H](O2)C(C(=O)OCC(C)C)[C@H]3C1=O
Answer: b. CCc1ccccc1N1C[C@@]23C=C[C@@H](O2)C(C(=O)OCC(C)C)[C@H]3C1=O
