If screen is shifted in $x$ direction away from the source, then which of the following is incorrect?

Fringe width $\beta =\frac{D\lambda }{d}$ and so with the increase in $D$, fringe width will increase. As angular fringe width $\alpha =\frac{\lambda }{d}$ and so it is independent of $D$. Distance of nth maxima from centre of the screen is given by $y_n=\frac{n\lambda D}{d}. As D increases , y_{n }also increases.$
