Problem statement: Answer the multiple-choice question.
Question: Which drug has a -3.955\% 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) CC(Nc1cc(=O)n(C)c(=O)[nH]1)c1ccccc1
b) COc1ccc(C2C3=C(CC(C)(C)CC3=O)Nc3c2c(=O)n(C)c(=O)n3C)cc1OC
c) O=C(NCc1cccnc1)C(=O)NC1CCCCC1
Answer: c. O=C(NCc1cccnc1)C(=O)NC1CCCCC1
