Task: Answer the multiple choice question.
Question: Which drug has a 13.168\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CCC(C)NS(=O)(=O)c1ccc(NS(C)(=O)=O)cc1
b. O=C(O)C1CCCN1C(=O)Nc1ccccc1
c. FC(F)(F)c1nnc2ccc(N3CCN(c4ccccc4)CC3)nn12
d. CCOC(=O)C(CC)/C(C)=N/NC(=O)c1ccccc1[N+](=O)[O-]
Answer: b. O=C(O)C1CCCN1C(=O)Nc1ccccc1
