Answer 1

Hint:
The mica gathering of sheet silicate (phyllosilicate) minerals incorporates a few firmly related materials having almost amazing basal cleavage.

Complete answer:
The word mica is gotten from the Latin word mica, which means a piece or a crumb. Mica is a mineral composed of a progression of plates or leaves. It splits effectively into flimsy sheets. These sheets can be slender to such an extent that 1,000 can be layered into a mica sheet of a couple of centimeters high.

Mica stores are found in the northern edge of the Chota Nagpur level. Koderma Gaya – Hazaribagh belt of Jharkhand is the main maker.

There are different explicit utilizations of this Mica sheet that are widely utilized in laser gadgets, aviation segments in ground-air-ocean dispatched rocket frameworks, radar frameworks and clinical hardware. This mineral is additionally precisely stable in micrometer sheets that are similarly straightforward to radiation while being impermeable to most gases.

Hence, the correct answer is option B.

Note:
Mica can be clear, dark, green, red yellow or earthy coloured. Because of its brilliant di-electric strength, low force misfortune factor, protecting properties and protection from high voltage, mica is one of the most imperative minerals utilized in electric and electronic enterprises.
