The Employment Assurance Scheme is designed primarily to assist rural parts of a country and aims to guarantee minimum employment to poverty-stricken families, not to all individuals seeking jobs. Hence, the scheme does not focus on providing employment to a specific percentage of men and women seeking jobs, rendering options 1 and 2 incorrect.

Option 3 is correct as this scheme focuses more on assisting families living below the poverty line by providing employment to at least one man and one woman in a rural family. This is in-line with the core objective of the scheme, which is to reduce poverty by providing employment opportunities to the poorest families in rural areas.

Option 4, "None of the above," is incorrect since Option 3 accurately describes what the Employment Assurance Scheme envisages.
