Task: Answer the multiple choice question.
Question: Which compound has a 9.465\% 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) Fc1nc(F)c(F)c(NCCCNc2c(F)c(F)nc(F)c2F)c1F
b) O=C(CCCC(=O)n1cnc2ccccc21)n1cnc2ccccc21
c) CC1=C(C(=O)Nc2ccccn2)C(c2cn(C)nc2C)C2=C(CCCC2=O)N1
d) CN(C)N1C(N)=C(C#N)C(c2cccs2)C2=C1CCCC2=O
Answer: b. O=C(CCCC(=O)n1cnc2ccccc21)n1cnc2ccccc21
