Option- 1: Statement 1 states that the Convention on the Rights of the Child recognizes the human rights of children up to the age of 14 years. This statement is incorrect. The Convention actually recognizes the human rights of all children up to the age of 18 years.

Option- 2: Statement 2 states that the Convention serves as a common reference to assess progress in meeting human rights standards for children. This statement is correct. The Convention provides a framework and standards for governments to ensure the protection and well-being of children, and progress in achieving these standards can be measured using it.

Based on the analysis above, the correct answer is option 2, which states that only statement 2 is correct.

Overall, the Convention on the Rights of the Child is an international treaty that recognizes the human rights of children up to the age of 18 years. It serves as a benchmark to assess and compare progress in meeting human rights standards for children.
