Problem statement: Answer the multiple-choice question.
Query: Which drug has a -6.101\% 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) COc1ccc(C2/C=C\CN(C(=O)Nc3ccccc3)CC(=O)N2Cc2ccc(F)cc2)cc1
(b) CCOC(=O)C(C)/C(C)=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
(c) Cc1cc(C)cc(NC(=O)C/C(N)=N/O)c1
Answer: b. CCOC(=O)C(C)/C(C)=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
