As per the passage what are the four names of the Vedas?

Context: In the most generic context, a Samhita may refer to any methodical collection of text or verses: Any shastra, sutra, or Sanskrit Epic, along with Vedic texts, might be referred to as a Samhita.Samhita, however, in contemporary literature typically implies the earliest, archaic part of the Vedas. These contain mantras – sacred sounds with or without literal meaning, as well as panegyrics, prayers, litanies and benedictions petitioning nature or Vedic deities. Vedic Samhita refer to mathematically precise metrical archaic text of each of the Vedas.The Vedas have been divided into four styles of texts – the Samhitas, the Brahmanas, the Aranyakas, and the Upanishads. The Samhitas are sometimes identified as karma-khanda, while the Upanishads are identified as jnana-khanda. The Aranyakas and Brahmanas are variously classified, sometimes as the ceremonial karma-khanda, other times as the jnana-khanda.The Vedic Samhitas were chanted during ceremonies and rituals, and parts of it remain the oldest living part of Hindu tradition.A collective study of Vedas and later text suggests that the compendium of Samhitas and associated Vedic texts were far larger than currently available. However, most have been lost at some point or over a period of Indian history.
