Isnt it supposed to be an intracellular signal molecule?
I go with cAMP.

tiz_83,
high levels of AMP signal the phosphrylation of f6p. Not cAMP
In addition, F26P in this case is considered an intracellular signal.

But I was referring to glucagon inhibiting PFK2 via cAMP dependent protein kinase A and lowering F 2,6 BP and thereby regulating phosphorylation of Fructose 6 phosphate

that could be correct and I see your point. However, the question does not state directly or indirectly. In this case, F26P would be directly and cAMP would be indirectly. What do you think>?
