What will be the product?

Analyse the following reaction. If
${\mathrm{HOCH}}_2{\mathrm{CH}}_2{\mathrm{COCH}}_2{\mathrm{CH}}_2{\mathrm{CO}}_2\mathrm{Et}\stackrel{1{\mathrm{CH}}_3\mathrm{MgX}}{⟶}\mathrm{P}\stackrel{1{\mathrm{CH}}_3\mathrm{MgX}}{⟶}\mathrm{Q}\stackrel{1{\mathrm{CH}}_3\mathrm{MgX}}{⟶}\mathrm{R}$

Which is/are correct?

${\left({\mathrm{CH}}_3\right)}_3\mathrm{CMgCl}$ on reaction with ${\mathrm{D}}_2\mathrm{O}$ produces

$\mathrm{R}-\mathrm{Br}\stackrel{\mathrm{Mg}/\mathrm{ether}}{⟶}\mathrm{A}\stackrel{{\mathrm{D}}_2\mathrm{O}}{⟶}{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{D}, \mathrm{R}-\mathrm{Br}$ by Wurtz reaction forms

Predict the major product in the following reaction:
