A lift is coming from $8^{th}$ floor and is just about to reach $4^{th}$ floor to stop there$.$ Taking ground floor as origin and positive direction upwards for all quantities, which one of the following is correct $?$

As lift is coming from $8^{\mathrm{th}} \mathrm{to} 4^{\mathrm{th}}$ floor and it is just reaching to $4^{\mathrm{th}}$ floor$,$ it is retarding. $\mathrm{I}.\mathrm{e}.$ acceleration a is acting upwards so,$a > 0.$ And the displacement $x$ is in downward direction hence negative$, \mathrm{i}.\mathrm{e}, \mathrm{x}<0,$ also velocity is downwards $(\mathrm{i}.\mathrm{e}.$ negative$)$ so$, v<0.$
