The correct answer is (a) The Vedas.
The Vedas are a collection of sacred Hindu texts that are considered to be the oldest scriptures of Hinduism. They are believed to have been composed in ancient India, and they contain a wealth of information about the Vedic Age, which was a period of time in Indian history that lasted from around 1500 to 500 BCE.
The Vedas are divided into four parts: the Rig Veda, the Yajur Veda, the Sama Veda, and the Atharva Veda. The Rig Veda is the oldest and most important of the Vedas, and it contains hymns that are addressed to the gods. The Yajur Veda contains instructions for performing Vedic rituals, the Sama Veda contains melodies that are used in Vedic rituals, and the Atharva Veda contains spells and incantations.
The Vedas are a valuable source of information about the Vedic Age because they provide insights into the religious beliefs, social customs, and political structures of that time period. They also contain information about the history of India, and they are an important part of the Hindu tradition.
The other options are incorrect because they are not literary sources of information about the Vedic Age. The Mahabharata is an epic poem that tells the story of the Kurukshetra War, and it was composed in the 4th century BCE. The Arthashastra is a treatise on political science that was written by Kautilya in the 4th century BCE. The Edicts of Ashoka are a series of inscriptions that were written by Ashoka the Great, who was an emperor of the Mauryan Empire in the 3rd century BCE.
