Task: Answer the multiple-choice question.
Question: Which drug has a 16.900\% 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: Nc1cc(N2CCNCC2)c([N+](=O)[O-])cc1Cl
b: CCCCC(=O)N/N=C/c1c(O)n(Cc2ccco2)c(=O)[nH]c1=O
c: Cc1cccc(OCCCC(=O)NC(C)c2ccccc2)c1
Answer: b. CCCCC(=O)N/N=C/c1c(O)n(Cc2ccco2)c(=O)[nH]c1=O
