Concept: A historical association must distinguish the role a person had at a place: studying or teaching at a centre of learning is different from serving at a royal capital. An explicit biographical or official-source association carries the conclusion; chronology and the institution’s character provide supporting checks but are not sufficient by themselves.

Application: Kautilya, also known as Chanakya or Vishnugupta, is traditionally placed in the fourth century BCE and is associated with the Arthashastra, a treatise on statecraft and economic administration. The standard biographical tradition used by the official BPSC key associates his teaching of political science and economics with Takshashila, an established centre of learning in Gandhara.

Cross-check and contrast:

• Nalanda became a major monastic university from about the fifth century CE, many centuries after Kautilya’s period.

• Pataliputra was the Mauryan imperial capital and is connected with Kautilya’s political and ministerial career; that is a different role from the teaching attribution asked here.

• Takshashila was active as a centre of advanced learning before and during the Mauryan age, and the teaching tradition is attached to this place.

• “More than one of the above” would require a second supported teaching location, while “None of the above” would require the absence of any supported location; neither condition follows from the historical attribution.

Result: Kautilya was associated with teaching political science and economics at Takshashila.
