why D or E not articulation point  ?
If removal of any vertex disconnects the graph that is articulation point or cut vertex

removing vertex F or A or G disconnects the graph so its articulation points

Removing D or E does not disconnects the graph.

A vertex in an undirected connected graph is an articulation point (or cut vertex) iff removing it (and edges through it) disconnects the graph 

Graph is having 3 articulation point F ,A &  G
