Hii buddy,
# Answers- x<0, v<0, a>0.
# Explaination-
a) Displacement-
As the lift is coming in downward direction, displacement will be negative. i.e. x<0
b) Velocity-
As displacement is negative, velocity must be negative. i.e. v<0
c) Acceleration-
The lift is about to stop at 4th floor, hence the motion is regarding. i.e. a>0
Hope this is helpful...
