**Explanation:**

The Vedas are the oldest sacred texts of Hinduism, composed in Sanskrit. They are considered to be the ultimate authority in Hindu philosophy and rituals. There are four main Vedas:

a) **Rigveda:** It is the oldest and most important Veda. It consists of hymns dedicated to various deities and contains the earliest form of Vedic Sanskrit.

b) **Yajurveda:** It contains prose and verse formulas that are used in rituals and ceremonies, particularly in sacrificial rituals.

c) **Samaveda:** It is a collection of melodies and chants that are sung during rituals. It is primarily a liturgical Veda, focusing on the musical aspects of rituals.

d) **Atharvaveda:** It contains hymns and spells for everyday life, such as healing, protection, and prosperity. It is considered to be a more recent addition to the Vedas and deals with practical aspects of life.

**Therefore, the correct answer is option 'B' - Saraswati.**

Saraswati is not a Veda but a Hindu goddess of knowledge, music, arts, and learning. She is considered to be the wife of Lord Brahma, the creator in Hindu mythology. Saraswati is often depicted as a serene and beautiful goddess, holding a veena (a musical instrument) and a book. She is regarded as the patron deity of education and the arts. While she is highly revered in Hinduism, she is not one of the four Vedas.

It is important to note that the Vedas are considered to be divinely revealed knowledge and are highly regarded in Hindu religious and philosophical traditions. They form the foundation of Hindu rituals, ceremonies, and spiritual practices. The Vedas have been preserved through oral transmission for centuries and are still studied and recited by scholars and priests in Hindu communities.
