The correct answer is: A. Karandev
Karandev was the last Hindu ruler of Gujarat. He was the son of Visaladeva and ruled from 1286 to 1296. He was defeated by Alauddin Khalji in 1296 and Gujarat was annexed to the Delhi Sultanate.
Karandev was a capable ruler and a patron of the arts. He built several temples and mosques in Gujarat. He was also a poet and wrote a number of poems in Sanskrit.
Karandev was succeeded by his son, Jayasimha, who was also a capable ruler. However, Jayasimha was defeated by Alauddin Khalji in 1299 and Gujarat was annexed to the Delhi Sultanate.
The other options are incorrect because:
- Visaladeva was the father of Karandev and ruled Gujarat from 1249 to 1286.
- Mularaja was the founder of the Chaulukya dynasty and ruled Gujarat from 1094 to 1104.
- Tribhuvanapala was the son of Mularaja and ruled Gujarat from 1104 to 1117.
