Two statements are given, one is labelled as Assertion (A) and the other as Reason (R):

Assertion (A): Defining a nation solely on the basis of common cultural characteristics is difficult.

Reason (R): Every possible criterion used to define a nation has notable exceptions and counter-examples.

Both (A) and (R) are true and (R) is the correct explanation for (A)

The correct answer is Option 1: Both (A) and (R) are true and (R) is the correct explanation for (A).

Assertion (A): Defining a nation solely on the basis of common cultural characteristics is difficult. — True. A nation cannot be defined by any single cultural characteristic such as language, religion, ethnicity or history. Different nations may not share the same cultural features, and the same cultural feature may be found across multiple nations. Therefore, no single cultural characteristic can universally define a nation.

Reason (R): Every possible criterion used to define a nation has notable exceptions and counter-examples. — True. The chapter explains that for every proposed criterion—common language, religion, ethnicity or history—there are exceptions. Some nations lack these common features, while many of these features extend beyond national boundaries.

Why (R) explains (A): The Reason directly explains the Assertion. Since every criterion used to define a nation has exceptions and counter-examples, it is difficult to identify any single cultural characteristic that all nations must possess. Hence, both statements are true and the Reason correctly explains the Assertion.

NCERT: A nation is a peculiar sort of community that is easy to describe but hard to define. We know and can describe many specific nations founded on the basis of common cultural, historical and political institutions like a shared religion, language, ethnicity, history or regional culture. But it is hard to come up with any defining features, any characteristics that a nation must possess. For every possible criterion there are exceptions and counter-examples. For example, there are many nations that do not share a single common language, religion, ethnicity and so on. On the other hand, there are many languages, religions or ethnicities that are shared across nations. But this does not lead to the formation of a single unified nation of, say, all English speakers or of all Buddhists.
