Which one of the following equations related to the motion of an object is NOT correct? (Symbols carry their usual meanings)

The correct kinematic equations of motion for uniformly accelerated motion are: (1) v = u + at, (2) s = ut + ½at², (3) v² − u² = 2as (NOT u² − v² = 2as), and (4) distance in nth second = u + ½a(2n − 1). Option (a) is correct, option (b) is correct (rearrangement of v = u + at gives u = v − at), option (d) is correct, but option (c) is incorrect because the correct form is v² − u² = 2as, not u² − v² = 2as.
