Task: Answer the multiple choice question.
Question: Which compound has a 5.494\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(NCCc1ccc(C(F)(F)F)cc1)c1ccc2c(c1)OCO2
b) COc1ccc(OC)c(N/C(C)=C/C(=O)c2ccccc2)c1
c) O=[N+]([O-])c1ccccc1/C=C/C=N/n1c(-c2ccccc2F)n[nH]c1=S
Answer: b. COc1ccc(OC)c(N/C(C)=C/C(=O)c2ccccc2)c1
