Brahmanism, a direct predecessor to hinduism, was based on texts called

brahmans.
upanishads.
vedas.
nobel truths.

The correct answer is Vedas. Brahmanism is based on the four ancient Sanskrit texts called Vedas. They are compilations of hymns, collections of prayers, formulas of consecration and atonement addressed to the gods:

-The Rigveda (the 'Veda of hymns'), the oldest text in Indian literature, from the middle of the second millennium BC. It is an epic-religious text with 1028 hymns (called rik) dedicated to multiple gods.

-The Samaveda (or 'Candable Veda'), which consists of 96% of Rig-veda hymns, arranged in a different way.

-The Yajurveda (or 'Veda of sacrifice'), which consists of a third of Rig-veda hymns.

-The Atharvaveda (or 'the Veda of the wise Atharvan'), consists of hymns to counteract spells in a fire sacrifice.

According to tradition, the Vedic hymns were revealed to the rishi (erudites), who more than authors are considered "listeners".
