21. 

Fructose-2,6-bisphosphate

[A]. activates fructose-1,6-bisphosphatase
[B]. activates phosphofructokinase
[C]. inhibits fructose-1,6-bisphosphatase
[D]. both (b) and (c)

Answer: Option D

Why B& C?

I think answer is A&B.

Because,

Fructose-2, 6-bisphosphate activates phosphofructokinase and 1, 6-bisphosphatase.

Since fructose 2, 6-bisphosphate activates PFK1 (a step in glycolysis) and inhibits fructose 1, 6-bisphosphatase (a step in gluconeogenesis) the body makes sure that glycolysis and gluconeogenesis aren't running simultaneously.

Fructose-2, 6bis phosphate inhibits phoshphofruktokinase-2(PFK-2).
PFK-2 : It catalise fructose-6-P into fructose-1,6-bis phosphate.

Thus indirectly fructose-2, 6-bis phosphate inhibits fructose-1,6-bis phosohate.
