Here linear doesn't mean one degree equation. It is asking about motion of body.

I think it should be S=ut-1/2at^2.

Answer D is correct.
All three equations of motion correspond to solve linear motion (m) where no equation involves angular motion (θ).

First Equation of Motion (Velocity-Time relation):v = u + at.
Relates initial velocity (u), final velocity (v), acceleration (a), and time (t).
Second Equation of Motion (Position - Time relation):s = ut + 1/2at^2.
Relates displacement (s), initial velocity (u), time (t), and acceleration (a).
Third Equation of Motion (Position-Velocity relation):v^2 = u^2 + 2as.
Since, all three choices listed are standard kinematic equations for uniformly accelerated linear motion, all of these are the correct choices.
