The correct answer is: C. The year 1000-1300 A. D.
The Chalukyas or Solankis ruled over Gujarat for almost three and a half centuries between 1000 and 1300 A.D. They were a powerful dynasty that originated in the Deccan region of India. The Chalukyas were known for their military prowess and their patronage of art and architecture. They built many temples and palaces, some of which are still standing today. The Chalukyas were eventually overthrown by the Mughals in the 16th century.
The other options are incorrect because they do not accurately reflect the time period during which the Chalukyas ruled over Gujarat. Option A is incorrect because it includes the year 900, which is before the Chalukyas came to power. Option B is incorrect because it includes the year 990, which is after the Chalukyas came to power. Option D is incorrect because it includes the year 950, which is before the Chalukyas came to power.
