What was the Early-Medieval period?

The correct answer is Option (1) → 650-1206

Historians divide India’s medieval period into two parts. The early medieval period runs from about 650 AD, after the death of Harsha (647 AD) broke up the last large kingdom of the north, to 1206 AD, when the Delhi Sultanate was founded by Qutb-ud-din Aibak. It was the age of regional kingdoms such as the Rajputs, Palas, Pratiharas, Rashtrakutas and Cholas. The later medieval period runs from 1206 to the 18th century.
