Answer 1

Hint: 1)He is known as the prince who united the Yuezhi Confederation during the 1st century.
2)He was also the great grandfather of Kanisha I, the greatest emperor in the Kushan Dynasty.

Complete answer:
He was the first emperor of the Kushan Dynasty and is known as the prince who united the Yuezhi Confederation during the 1st century. The Kushans are considered as one of the five branches of the Yuezhi Confederation. Yuezhi confederation was a group of Indo-European people who lived nomadic pastoral lives in the grasslands of western China. Heraios, the chief of the Kushana Clan in the Yuezhi Confederation was the ancestor of Kajula.
We know about Kajula from the Chinese inscriptions, where it has been said that the rise of the Kushan Dynasty was the result of a gory Civil war. Kujula, who is referred in the Chinese texts as Quijiuque, attacked and exterminated the heads of the other four clans of the Yuezhu Confederation and established himself as the King.
His reign
He then invaded Gaofu (present day Kabul) and Anxi (part of Indo-Parthian Kingdom). He also defeated entire kingdoms of Puda and Jibin. The exact locations of the area under Puda and Jibin Kingdoms are unknown, but it is pretty clear that they were in Central Asia too.
Being in Central Asia, the coinage of the Kushan Dynasty has influence from both India and Europe. The majority of the coins minted under the Kushan Empire had Roman and Greek inscriptions. Some of the coins also referred to him as the Indo-Greek king. He gave himself this title, being inspired by the actual Indo-Greek king, Hermaius who ruled over the same area, 80-90 years before Kajula. He lived a very long life and died at the age 84 in Multan, Pakistan.
Option (B) Vima kadphises: This option is incorrect. He was the Grandson of Kajula Kadphises and the father of the Great Kanishka I.
Option (C) Kanishka: This option is incorrect. He was also called Kanisha the Great. He was the great grandson of Kajula Kadphises and the greatest Kushan ruler in history.
Option (D) Vasudeva: This option is incorrect. He was the grandson of Kanishka and the last ruler of the Great Kushans. He was also the first Kushan king to be named after an Indian God.

Hence, the correct answer is option (A)

Note: 1)After deciphering the Rabatak inscriptions we know that Kajula Kadphises was the great grandfather of Kanisha I.
2)Kanishka I is also called Kanishka the Great and is considered as the greatest emperor in the Kushan Dynasty.
