What is compression?

Answer 1

Stress squeezing an object

Answer 2

Compression is stress squeezing an object. The correct option is A.

The word compression can be defined by the dictionary as an external force (stress) that tends to crush a material, squeezing its particles closer and shortening the dimension in the direction of its action.  

Squeeze refers to manage an object to get into or through a narrow or restricted space; firmly press (something soft or yielding), typically with one's fingers.
