Consider the following events: I. Reign of Krishna Deva Raya of Vijayanagara. II. Construction of Qutab Minar. III. Arrival of Portuguese in India. IV. Death of Firoz Tughlaq.

To solve this question, we must look at the specific dates or periods of each event to establish the correct chronological order. I. Reign of Krishna Deva Raya of Vijayanagara: He ruled from 1509 to 1529. II. Construction of Qutab Minar: Construction was started by Qutub ud din Aibak around 1192 and completed by Iltutmish around 1220. III. Arrival of Portuguese in India: Vasco da Gama reached Calicut in 1498. IV. Death of Firoz Tughlaq: He was a Sultan of the Tughlaq dynasty who died in 1388. Chronological Order: The earliest event is the construction of the Qutab Minar in the early 13th century (II). This is followed by the death of Firoz Tughlaq in the late 14th century (IV). Next is the arrival of the Portuguese at the end of the 15th century (III). Finally, the reign of Krishna Deva Raya occurs in the early 16th century (I). Therefore, the correct sequence is II, IV, III, I, which matches Option A.
