Task: Answer the multiple choice question.
Question: Which drug has a 4.353\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) CCC(C)(CC(=O)N(C)CCC#N)c1ccccc1
b.) O=C(NCCc1ccccc1)C(=O)NCC1CCCO1
c.) COC(=O)C(=N/Nc1ccccc1C(=O)OC)/C(C)=N/O
d.) CC(C)CC(O)(CC(C)C)C(=O)NNc1ccccc1
e.) O=C(O)CCC(=O)N1CCOc2ccc(Cl)cc21
Answer: b. O=C(NCCc1ccccc1)C(=O)NCC1CCCO1
