Consider the following reactions: 

$Si{O}_2+2NaOH\to X+Y$

$Si{O}_2+4HF\to R+2Y$

$R+2HF\to Q$

$3R+4H_{2}O\to Q+M$

Then identify the correct statements? 

Similar to $SiC{l}_4$, R also readily undergoes complete hydrolysis under normal conditions

M on strong heating gives $Si{O}_2$ as one of the product

In the anionic part of Q, the central atom is in the  $s{p}^3{d}^2$ hybridized state

M is also obtained as one of the product by the hydrolysis of  $SiC{l}_4$
