Problem statement: Answer the multiple-choice question.
Query: Which compound has a 3.281\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COCC(=O)N/N=C(\C)CC(=O)NCc1ccco1
(b) COc1ccc(NC(=O)COC(=O)CCNS(=O)(=O)c2ccccc2)cc1OC
(c) Cc1ccc(OCC(=O)c2ccc(Cl)s2)c([N+](=O)[O-])n1
(d) COc1ccc(C/C(N)=N/OC(=O)c2ccco2)cc1OC
Answer: a. COCC(=O)N/N=C(\C)CC(=O)NCc1ccco1
