The correct answer is C. 8 September.
World Literacy Day is observed on 8 September every year. It was proclaimed by UNESCO in 1966 to highlight the importance of literacy as a fundamental human right and essential for the exercise of all other human rights. The day also marks the anniversary of the signing of the UNESCO Literacy Declaration in 1965.
Literacy is the ability to read and write. It is a basic skill that is essential for participation in society and for economic development. Literacy is also a key factor in reducing poverty and improving health and well-being.
According to UNESCO, 757 million adults in the world are illiterate. This means that they cannot read and write a simple sentence. Illiteracy is a major obstacle to development. It prevents people from accessing information, participating in decision-making, and improving their lives.
World Literacy Day is an opportunity to raise awareness of the importance of literacy and to promote efforts to achieve universal literacy. The day is also a time to celebrate the achievements of those who have overcome illiteracy.
The other options are incorrect because they are not the dates on which World Literacy Day is observed.
