Consider the relation $R(P,Q,S,T,X,Y,Z,W)$  with the following functional dependencies.

$PQ\rightarrow X;\quad P\rightarrow YX;\quad Q\rightarrow Y; \quad Y\rightarrow ZW$

 Consider the decomposition of the relation R into the constituent relations according to the following two decomposition schemes.

$D_1:\quad R=[(P,Q,S,T);\;(P,T,X);\;(Q,Y);\;(Y,Z,W)]$

$D_2:\quad R=[(P,Q,S);\;(T,X);\;(Q,Y);\;(Y,Z,W)]$

Which one of the following options is correct?
