The Correct Option is C

Solution and Explanation

Concept:
Glass formers are materials responsible for creating the glassy structure in ceramic glazes.


Step 1:
Flint is a source of silica and acts as a glass former. Thus: \[ A \text{ is correct} \]


Step 2:
Quartz contains silica and contributes to glass formation. Thus: \[ C \text{ is correct} \]


Step 3:
Silica is the principal glass former in ceramic glaze. Thus: \[ D \text{ is correct} \]


Step 4:
Alumina mainly stabilizes glaze while bentonite acts as a suspending agent. \[ \boxed{\text{(3) A, C and D Only}} \]
