Task: Answer the multiple choice question.
Question: Which drug has a 5.375\% 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: COc1ccc(C2C3=C(NCCN=C3c3ccccc3)C(=O)N2c2ccccc2)c(OC)c1
b: CCCCC(CC)C(=O)Nc1ncc([N+](=O)[O-])s1
c: Cc1cc(OCC(=O)N2CCN(c3ncccn3)CC2)ccc1Cl
Answer: b. CCCCC(CC)C(=O)Nc1ncc([N+](=O)[O-])s1
