Which article of the Charter focuses on the integration of persons with disabilities?

The correct choice emphasizes Article 26 of the Charter, which specifically addresses the integration of persons with disabilities. This article recognizes the importance of promoting the full participation of individuals with disabilities in all aspects of life, ensuring their inclusion in society. It outlines the necessity for states to implement laws and policies that support the empowerment of persons with disabilities, promoting their accessibility and ensuring they can participate fully in economic, social, and cultural activities. The focus on integration underscores the need to remove barriers and create environments that support equality and accessibility for all.

The other choices address different aspects of rights and non-discrimination but do not specifically center on integration. For instance, Articles 18, 21, and 32 pertain to other rights and principles that support the broad framework of disability rights but do not specifically highlight the theme of integration as effectively as Article 26 does.
