Task: Answer the multiple choice question.
Question: Which drug has a 0.861\% human ether-à-go-go related gene (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) CCCCn1c(N)c(N(CC(C)C)C(=O)C2CC(=O)N(c3ccc4c(c3)OCCO4)C2)c(=O)[nH]c1=O
b) COc1ccc(OCC(O)COc2ccc(OC)cc2)cc1
c) CCc1ccccc1NC(=O)c1ccc([N+](=O)[O-])s1
Answer: c. CCc1ccccc1NC(=O)c1ccc([N+](=O)[O-])s1
