Correct Answer:
B. Age 10+
The literacy rate in Pakistan is a crucial indicator of educational development and is measured based on a specific age group. According to national surveys and census data in Pakistan, the literacy rate is defined as the percentage of the population aged 10 years and above who can read and write a simple statement in any language with understanding. This threshold helps capture the segment of the population that has typically completed basic schooling and acquired foundational literacy skills.
- Age 5+ (A) is generally considered too young, as children at this age are often just beginning their formal education and may not have achieved full literacy.
- Age 15+ (C) is a common international standard used by organizations like UNESCO, but Pakistan specifically adopts the 10+ age criterion for its national statistics.
- Age 18+ (D) is too high an age threshold, as most individuals who achieve literacy do so well before reaching adulthood.
