The foreign traveller who was a qazi in the court of Muhammad Bin Tughlaq:[1](May have multiple correct answers)AIbn BatutaBAl BeruniCMarco PoloDNicolo Conti

The foreign traveler who was a qazi in the court of Muhammad Bin Tughlaq is Ibn Batuta. He was a Moroccan explorer and Islamic scholar who traveled extensively throughout the Islamic world and beyond, including India during the reign of Muhammad Bin Tughlaq. Ibn Batuta served as a qazi, or judge, in the sultan's court.

While Al Beruni, Marco Polo, and Nicolo Conti were also significant travelers and scholars, they did not serve in the court of Muhammad Bin Tughlaq. Al Beruni was known for his work on the scientific and cultural aspects of India, Marco Polo traveled primarily in Asia but did not visit India during Tughlaq's reign, and Nicolo Conti visited India later in history. Thus, the most accurate answer is Ibn Batuta.
