Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.627\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COc1ccc(OCCCc2c(C)n[nH]c2C)cc1
b) CCCc1cc(-n2ccnc2)n2c(nc3ccccc32)c1C#N
c) CCN(CC)C(=O)CN1C(=O)C2CC=C(Cl)CC2C1=O
Answer: c. CCN(CC)C(=O)CN1C(=O)C2CC=C(Cl)CC2C1=O
