Who among the following traveller was impressed by the fortification of the Vijayanagara and mentioned about seven lines of defense in forts?

Abdur Razzaq

The correct answer is Option (2) → Abdur Razzaq

Abdur Razzaq, an ambassador sent by the ruler of Persia to Calicut (present-day Kozhikode) in the fifteenth century, was greatly impressed by the fortifications, and mentioned seven lines of forts. These encircled not only the city but also its agricultural hinterland and forests. The outermost wall linked the hills surrounding the city.
