The correct answer is option 4 - Gandhara. Gandhara art style refers to the blend of Indian and Greek artistic traditions that emerged in the region of Gandhara, located in present-day Pakistan and Afghanistan, during the 1st to 7th century CE. This art style evolved as a result of the cultural exchange between the Greek and Indian civilizations during the time of Alexander the Great`s conquests.
The Gandhara art style is characterized by the fusion of Greek and Indian elements, such as the use of Greek techniques and motifs combined with the traditional Indian iconography. This resulted in sculptures that featured realistic and naturalistic figures with drapery influenced by Greek artistic conventions. The Gandhara art style played a significant role in the development of Buddhist art in the region, with the depiction of Buddha and Buddhist narratives being prominent subjects in Gandhara sculptures.
