What is aluminosilicate? Which ions are used to balance its electric charge?

Which of the following gives $SO_2$ with dilute $H_2SO_4$?

Consider the following reactions:
$Me_3SiCl \xrightarrow{H_2O} A$
$Me_2SiCl_2 \xrightarrow{H_2O} B$
$MeSiCl_3 \xrightarrow{H_2O} C$
$A$,$B$,and $C$ are known as . . . . . . , . . . . . . ,and . . . . . . respectively in silicones formation.
