Option E is correct because conclusion says In a way, although politicians are considered representatives of a society, those having awareness of social trends are rare to find.It means although its rare to find those politicians, there are some politicians who are no less aware of social trends than typical common men

A. Wrong. Passage mentions that politicians with awareness of social trends are rare to find, and from this information we can infer that there are at least a few or more politicians who are just as aware as the common man about changing social trends.

B. Wrong. Just because politicians are ignorant of changing social trends we can't conclude that experience in politics is the reason for their ignorance. This causality has no leg to stand on.

C. Wrong. This option is making a too extreme inference.

D. Wrong. This option is tricky, but incorrect, because it brings in to discussion the word "behavior". The argument is concerned with just one aspect of behavior, which is awareness of changing social patterns, to compare people and politicians, and not the complete behavior.

E. Correct. This statement can be inferred from the information given in the last line of the passage.
