Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.311\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCOc1cc(C(=O)Nc2cccc(OCC(=O)N3CCOCC3)c2)cc(OCC)c1OCC
b O=C(Nc1ccc2ccccc2c1)c1ccc(Cl)cc1Cl
c O=C(CSc1nnnn1C1CCCC1)Nc1ccccc1F
d O=C(CNC(=O)Cc1ccccc1)NCC(=O)OCc1ccccc1
Answer: c. O=C(CSc1nnnn1C1CCCC1)Nc1ccccc1F
