The correct answer is option 4, Angas. The Jaina literature is a collection of ancient texts and scriptures that are unique to the Jaina religion. The Jaina literature is known as Angas, which means "limbs" or "parts" in Sanskrit. These Angas are considered to be the primary canonical texts of Jainism and are divided into twelve parts.
Option 1, Tripitakas, refers to the sacred scriptures of Buddhism, not Jainism.
Option 2, Epics, refers to long narrative poems or stories, such as the Mahabharata or Ramayana, which are not specific to the Jaina literature.
Option 3, Aiyasutras, is an incorrect term and does not refer to any known Jaina text.
Therefore, option 4, Angas, is the correct answer for the Jaina literature.
