Explanation:

• The Pratiharas were also called Gurjara. They ruled between the 8th and 11th century A.D. over northern and western India.
• The Pratiharas stood as a fortification of India's defense against the hostility of the Muslims from the days of Junaid of Sind (725. A.D.) to Mahmud of Ghazni.
• Rulers of the Pratihara dynasty: o NagabhattaI (725-740 A.D.): Founder of the Pratihara dynasty with Kanauj as its capital.
• Mihirabhoja: The most powerful Pratihara king. During his period, the empire expanded from Kashmir to Narmada and from Kathiawar to Bihar. He was a devotee of Vishnu and took the title "Adivaraha". Hence pair 1 is correctly matched.
• Mahendrapala I (885-908 A.D.): Son of Mihirabhoja, was also a powerful ruler. He extended his control over Magadha and North Bengal. Hence pair 2 is not correctly matched.
• Rashtrakutas: While the Palas and the Pratiharas were ruling over north India, the Deccan were being ruled by the Rashtrakutas, a remarkable dynasty that produced a long line of warriors and able administrators.
• The Rashtrakuta empire was founded by Dantidurga who set up his capital at Manyakhet or Malkhed near modem Sholapur. The Rashtrakutas soon dominated the entire area of northern Maharashtra.
• Govinda III annexed Kanauj, Malwa, turned south, and defeated Lankan rulers.
• Amoghvarsha: preferred the pursuit of literature and religion to that of war. He wrote the first Kannada book on poetics. Faced many rebellions in far-flung areas of the empire. Hence pair 3 is correctly matched.
