Consider the following pairs :
Traveller : Century/ Centuries

I. Marco Polo : Tenth and eleventh centuries

II. Al-Biruni : Thirteenth century

III. Duarte Barbosa : Sixteenth century

How many of the pairs given above are correctly matched?

The pairs are evaluated as follows:

• Marco Polo: He was a Venetian traveler who visited India (specifically the Pandyan kingdom) in the late 13th century (c. 1292–1294 CE). The pair incorrectly attributes him to the 10th and 11th centuries.
• Al-Biruni: A Persian scholar who arrived in India in the 11th century (c. 1017 CE) along with Mahmud of Ghazni. He is famous for his work Kitab-ul-Hind. The pair incorrectly attributes him to the 13th century.
• Duarte Barbosa: He was a Portuguese official who served in India and visited the Vijayanagara Empire in the early 16th century (c. 1500–1516 CE). This pair is correctly matched.

Since only the third pair is correct, the answer is One.
