Problem statement: Answer the multiple choice question.
Query: Which compound has a 11.623\% hERG inhibition at a concentration of 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)c1cc2c([nH]c1=O)CCCC2
b: O=C(Nc1cccc(S(=O)(=O)N2CCCCCC2)c1)c1ccc(=O)[nH]c1
c: CCc1ccccc1N1C[C@@]23C=C[C@@H](O2)C(C(=O)OCC(C)C)[C@H]3C1=O
Answer: a. O=C(O)c1cc2c([nH]c1=O)CCCC2
