The correct answer is  Kushana.

• The Gandhara School of art was developed in the first century AD during the reign of Kushana emperor Kanishka.
• Both Shakas and Kushanas were patrons of Gandhara School, which is known for the first sculptural representations of the Buddha in human form.
• The art of the Gandhara school was primarily Mahayana and shows Greco-Roman influence.

• This style of art was closely associated with Mahayana Buddhism and hence the main theme of this art was Lord Buddha and Bodhisattvas.
• Thus, it can be conjectured that in idea and conception this style was Indian and in execution it was foreign.
• One example of the Gandhara style of art is the Bamiyan Buddha statues.
• It mostly flourished in the areas of Afghanistan and present North-Western India.
• The prominent locations were Taxila, Peshawar, Begram, and Bamiyan.
• The period around which the Gandhara school of art flourished could be said to be from the 1st century BCE to 4th century CE.
