Quartz is a crystal which is chemically silicon dioxide.

Lime stone is parent rock of quartz rock. Lime stone contain silica or lime as major constitute. Hence, answer is related to silica.

Quartz is obtained from the pure form of silicon dioxide. Quartz is a compound called silicon dioxide. When a crystal of quartz is properly cut and mounted, it can be made to vibrate, or oscillate, using an alternating electric current; each oscillation, in turn, causes a voltage change across the crystal, which can be detected by a suitable electronic circuit.

The frequency at which the crystal oscillates is dependent on its shape and size, and the positions at which electrodes are placed on it. If the crystal is accurately shaped and positioned, it will oscillate at a desired frequency; in clocks and watches, the frequency is usually 32,768 Hz, as a crystal for this frequency is conveniently small, and as this frequency is a power of two and can easily be counted using a 15-bit binary digital counter.

A hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite) ; yellow sand is quartz with iron oxide impurities.

It is widely used in clocks.

Quartz is crystalline silicon dioxide.

It is used in clock and vibrates too fast.

Anyone explain me in detail?

In sio2 only the quartz metal is found.

Quartz is obtained from the pure form of silicon dioxide (sand).

Which liquid is metal?
Chemically, quartz is a compound called silicon dioxide. When a crystal of quartz is properly cut and mounted, it can be made to vibrate, or oscillate, using an alternating electric current; each oscillation, in turn, causes a voltage change across the crystal, which can be detected by a suitable electronic circuit. The frequency at which the crystal oscillates is dependent on its shape and size, and the positions at which electrodes are placed on it. If the crystal is accurately shaped and positioned, it will oscillate at a desired frequency; in clocks and watches, the frequency is usually 32, 768 Hz, as a crystal for this frequency is conveniently small, and as this frequency is a power of two and can easily be counted using a 15-bit binary digital counter.

Is correct.

Quartz is crystal, but it is not a chemical product.

Quartz is a crystal and also silicon dioxide (sand).

A hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite); yellow sand is quartz with iron oxide impurities.

I think D should be answer.

Silicon Dioxide is correct.
