Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.751\% 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) CO/N=C(/CNC(=O)c1cccc(Cl)c1)c1ccc(Cl)cc1
b) O=C(O)CCC1(C(=O)O)OCCc2ccccc21
c) O=C1N(c2ccccc2)C[C@@H]2C[C@@H](c3cccs3)N3CCC[C@@]123
Answer: b. O=C(O)CCC1(C(=O)O)OCCc2ccccc21
