Answer : Option B
Explanation :
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.
