Sir David lyndsay’s satire of the three estatis is both

The correct option is Political and religious.

Sir David Lyndsay's seminal work, Ane Pleasant Satyre of the Thrie Estaitis (circa 1540), is a powerful morality play that serves as a critique of early modern Scottish society.
It is categorized as both political and religious because of how it targets the socio-political structures and ecclesiastical corruption of its time.

1. Political Satire:
The play directly critiques the "Three Estates" of the Scottish Parliament: the Clergy, the Nobility, and the Merchants/Burgesses. Lyndsay exposes the political corruption, the exploitation of the common people (represented by the character John the Common-Weill), and the failure of the temporal rulers (the Nobility and the Crown) to maintain justice, law, and good governance in the realm.

2. Religious Satire:
Writing on the eve of the Scottish Reformation, Lyndsay directs his sharpest satire at the Roman Catholic clergy. The play exposes ecclesiastical abuses such as simony, pluralism, spiritual ignorance, and the neglect of pastoral duties. It advocates for religious reform, emphasizing the need for the Bible and services to be in the vernacular language so that common citizens can understand them, and urges the clergy to return to a state of spiritual integrity.

Consequently, because the satire is deeply concerned with the reform of both state governance and the church, it is fundamentally characterized as both political and religious.
