The correct answer is: B. Post Mauryan period.
The Yaudheya were an ancient Indian tribe that lived in the region of Mathura in the northern Indian subcontinent. They were known for their military prowess and their resistance to the Mauryan Empire. The Yaudheya Republic was a confederacy of 16 tribes that ruled over the region from the 3rd century BCE to the 6th century CE.
The Yaudheya were first mentioned in the Mahabharata, where they are described as being one of the most powerful tribes in the Kurukshetra War. They were also mentioned in the Arthashastra, where they are described as being a major military power in the region.
The Yaudheya Republic was a powerful and independent state for many centuries. However, they were eventually conquered by the Gupta Empire in the 4th century CE. After the fall of the Gupta Empire, the Yaudheya Republic declined in power and eventually disappeared.
The Yaudheya were a significant tribe in the history of India. They were a major military power and they played an important role in the resistance to the Mauryan Empire. The Yaudheya Republic was a powerful and independent state for many centuries. However, they were eventually conquered by the Gupta Empire in the 4th century CE.

The other options are incorrect because:
- The Post Harappan period is the period after the decline of the Indus Valley Civilization. The Yaudheya Republic was not founded until the 3rd century BCE, which is much later than the Post Harappan period.
- The Post Gupta period is the period after the decline of the Gupta Empire. The Yaudheya Republic was already in decline by the time of the Gupta Empire, so it cannot be considered to be a part of the Post Gupta period.
- The Medieval period is the period from the 5th to the 15th centuries CE. The Yaudheya Republic had already disappeared by the 6th century CE, so it cannot be considered to be a part of the Medieval period.
