The correct answer is: D. India
Oil paint was first used for Buddhist paintings by Indian and Chinese painters in western India sometime between the fifth and tenth centuries.
Oil paint is a type of paint that uses oil as a binder. It is made by mixing pigment with a drying oil, such as linseed oil, walnut oil, or poppy seed oil. Oil paint is slow-drying, which allows artists to blend colors and create smooth transitions. It is also very durable, making it ideal for use on outdoor surfaces.
Oil paint was first used in China in the 5th century. It was introduced to India by Chinese Buddhist missionaries in the 7th century. Indian artists quickly adopted oil paint and began using it to create their own unique style of Buddhist paintings. These paintings are characterized by their use of bright colors, intricate details, and religious symbolism.
Oil paint continued to be used in India for Buddhist paintings until the 10th century. After that, it fell out of favor and was replaced by other types of paint, such as tempera and watercolor. However, oil paint has recently experienced a resurgence in popularity in India, and it is now used by both traditional and contemporary artists.
