Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -0.268\% 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 or b without using any additional words.
Options:
a. O=[N+]([O-])c1nn(-c2ccc3c(c2)OCCO3)n(O)c1=NCc1ccc(F)cc1Cl
b. O=C1C(C=NCCN2CCOCC2)=C(O)c2ccccc21
Answer: b. O=C1C(C=NCCN2CCOCC2)=C(O)c2ccccc21
