Solution

The correct option is D

A-→q; B-→s; C-→p; D-→r


  1. Thrust is defined as force acting on an object perpendicular to its surface and its unit is Newton (N);(A)----→(P)
  2. Relative density is defined as the ratio of density of a substance to the density of a reference substance ,since its ratio of two similar quantities it doesn't have unit
    relativedensity=densityofasolid/liquiddensityofreferencesubstance;referencesubstancemaybewater
    Thus (B)---→(s)
  3. Pressure is defined as the force applied to an object perpendicular to its surface per unit area ;pressure=ForceAreaanditsSIunitisPascal
    Hence option (C)----→(p)
  4. Density of an object is defined as mass of the substance per unit volume ;
    Density=massvolumeand its unit is kgm3
    Hence option (D)--→(r)
    Thus option (d) is the correct answer: A-→q; B-→s; C-→p; D-→r
