Answer:
c. Jade
Step-by-step explanation:
Jade is a rock combined with two different minerals such as jadeite and nephrite. Jadeite is the most valuable and scarce mineral variety, as well as the most difficult to find, while Nephrite already has localizable births. Jadeite can be obtained in Eastern territories such as: Tawmaw near Mogok in Burma; in some parts of the mountains of Tibet and Kazakhstan; in Longchuang in Yunnan province, China; and also in some mountains of Japan. In the Americas, it can be found in a Sierra de las Minas in Guatemala (in the arid region of Zacapa, 120 miles northwest of the Guatemalan capital) and, similarly, in Cloverdale, California, in the United States. Also, nephrite can be obtained in some states of Mexico.
