Task: Answer the multiple-choice question.
Query: Which drug has a -6.723\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) Cc1cc(C(=O)NCC(=O)OC(C)C(=O)N2CCOCC2)ccc1[N+](=O)[O-]
b) COc1ccc(C2C(C#N)=C(/N=C/N3CCN(C)CC3)OC3=C2C(=O)CC(C)(C)C3)cc1
Answer: b. COc1ccc(C2C(C#N)=C(/N=C/N3CCN(C)CC3)OC3=C2C(=O)CC(C)(C)C3)cc1
