$\textrm{Option A is wrong, why because the question is saying Y is not married with an engineer.}$

$\textrm{Option B is also wrong, Z is not married to Doctor.}$

$\textrm{Option C is also wrong, X is married to A who is a lawyer (Given in question).}$

$\textrm{Option D is true.}$

                $\textrm{X$\Leftrightarrow$A(Lawyer)}$

                $\textrm{Y$\Leftrightarrow$B(Doctor)}$

                $\textrm{Z$\Leftrightarrow$}C(Engineer)$

In the question, it is NOT given that there are only 3 professions, so we can’t and shouldn’t assume just because Y can’t be married to an Engineer means she must have married a doctor. Same goes for Z too

 

We can only say Y can marry B or C whose profession we don’t know !! Same goes for Z
