Assertion: Migration (even excluding the marriage migration) affects the status of women directly or indirectly.
Reasoning: In the rural areas, male selective out migration leaving their wives behind puts extra physical as well mental pressure on the women.

Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A.

Assertion: Migration (even excluding the marriage migration) affects the status of women directly or indirectly. This statement is true.  This assertion is broad and inclusive of both male and female migration, excluding marriage migration. It suggests that migration, regardless of gender, has implications for the status of women in society. This could involve changes in social roles, economic opportunities, access to resources, and overall well-being.

Reasoning: In the rural areas, male selective out migration leaving their wives behind puts extra physical as well mental pressure on the women.This is also true. The reasoning provided focuses specifically on the scenario in rural areas where male selective outmigration occurs, leaving wives behind. It highlights the extra physical and mental pressure faced by these women due to their husbands' absence. This pressure can result from increased responsibilities, decreased support networks, and changes in family dynamics.

Evaluation:

While the reasoning correctly addresses the challenges faced by women left behind due to male outmigration in rural areas, it does not fully explain how migration affects the status of women when they themselves migrate (excluding the marriage migration). The assertion encompasses all forms of migration, including both male and female migration, but the reasoning only addresses a specific scenario within rural male outmigration. Therefore, while both the assertion and reasoning are correct, the reasoning does not provide a comprehensive explanation for the assertion.

Thus, Option 2: Both Assertion (A) and reasoning (R) are correct, but R is not the correct explanation of A, is the appropriate choice.
