Task: Answer the multiple choice question.
Query: Which compound has a 3.420\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(O)CP(=O)(O)c1ccc(Cl)cc1
(b) CC/C(=N\NC(=O)CNC(=O)/C=C/c1ccco1)c1ccccc1
(c) CC(C)C(C)NC(=O)COc1ccc([N+](=O)[O-])cc1Cl
Answer: a. O=C(O)CP(=O)(O)c1ccc(Cl)cc1
