i am not agreed with OA

as rightly said by Paes " some people" :- there may be some people who knows how government works donot know how its formed

now come to argument its children of the country means all children not some people should know how government works
so they should be taught how government formed.

option B clearly strengthen the argument not weaken it
option B says about some people and argument says childrens or everyone

please convince or get convinced

Pradeep@

Brian has given good explanation in his last post.

Let me try to explain this with a simple conversation :

Pradeep : Every cricket commentator (to be good) should be a former player.
Paes : But there are some good commentators (such as Harsha Bhogle ) who are not former player.

So obviously I am weakening your argument .
