• A. 5-10%
• B. 2-5%
• C. 10-15%
• D. 1-2%

Answer: (B)

Dyscalculia is a specific learning disability that affects an individual’s ability to understand and manipulate numbers and mathematical concepts. Research suggests that the prevalence of dyscalculia in the general population typically falls within the 5-7% range. However, many studies and expert opinions place the recognized occurrence of dyscalculia at around 2-5%. This range reflects data that has been collected and analyzed over time, indicating that while dyscalculia may not be as widely recognized as dyslexia, it still affects a notable portion of the population, warranting attention in educational and psychological assessments.

Choosing the 2-5% range accurately captures the current understanding of dyscalculia's prevalence, reinforcing the importance of being aware of this learning disability in educational settings and ensuring that appropriate support and interventions are provided for affected individuals.
