A) \[CO\]
B) \[FeSi{{O}_{3}}\]
C) \[MgSi{{O}_{3}}\]
D) \[Casi{{O}_{3}}\]
Correct Answer: D
Solution :
In the iron silica is present as impurity, so for the removal of impurity of silica limestone is used. \[CaC{{O}_{3}}\xrightarrow{\Delta }CaO+C{{O}_{2}}\] \[CaO+Si{{O}_{2}}\xrightarrow{{}}\underset{\text{slag}}{\mathop{CaSi{{O}_{3}}}}\,\]
