Explanation
1. The question asks which rights are included in the United Nations Convention on the Rights of the Child (UNCRC).
2. The UNCRC is a comprehensive human rights treaty setting out the civil, political, economic, social, health, and cultural rights of children.
3. It is based on four core principles: non-discrimination; devotion to the best interests of the child; the right to life, survival and development; and respect for the views of the child.
4. Statement 1: The Right to Development is a core principle, encompassing physical, mental, spiritual, moral, and social development (Article 6, Article 27). This is included.
5. Statement 2: The Right to Expression (freedom of expression), including the right to seek, receive and impart information and ideas, is explicitly protected (Article 13). This is included.
6. Statement 3: The Right to Recreation, rest, leisure, play, and participation in cultural life and the arts is also explicitly recognized (Article 31). This is included.
7. Since all three rights listed (Development, Expression, Recreation) are covered by the UNCRC, the correct option is (D) 1, 2 and 3.
