‘Pithora’ refers to:

A type of wood
A tribal deity
A dance form
A weaving technique

The correct answer is: A tribal deity.

Pithora is a tribal deity worshipped by the Bhil people of central India. She is the goddess of fertility and protection, and is often depicted as a woman with a snake around her neck. Pithora is said to live in the mountains, and her devotees often make pilgrimages to her shrines.

The other options are incorrect. Pithora is not a type of wood, a dance form, or a weaving technique.
