Task: Answer the multiple choice question.
Query: Which compound has a 1.901\% 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 other words.
Options:
a) O=C(/C=C/c1ccc(F)cc1)N1CCCc2ccccc21
b) C=CCn1c(O)c(N=Nc2ccccc2O)c2ccccc21
Answer: a. O=C(/C=C/c1ccc(F)cc1)N1CCCc2ccccc21
