Explanation:

Hereditary

The succession of Delhi Sultans to the throne was generally hereditary, meaning that it followed a line of descent within a family. The eldest son or a chosen heir would often succeed the ruler upon their death, based on the principle of primogeniture or other established rules of succession. While conflicts among brothers or other contenders for the throne did occur at times, hereditary succession was the primary method of determining the next ruler in the Delhi Sultanate.
