Solution(By Examveda Team)

Muscovite, Phlogopite and Biotite are Mica varieties. Muscovite, often called ‘white mica’, is the lightest colored mica mineral. Usually colorless, white or silver, occasionally yellow or brown. Phlogopite is a yellow, greenish, or reddish-brown member of the mica family of phyllosilicates. It is also known as magnesium mica or amber mica. Biotite is a common phyllosilicate mineral within the mica group. The high content of iron ions gives it a dark hue. It is sometimes called "iron mica" because it is more iron-rich than phlogopite.
