Answer:
Option D is the correct answer.
Explanation:
Stress is the force per unit area that tend to change the shape of body.
Stress is defined as internal resistive force per unit area.
[tex]\texttt{Stress}=\frac{\texttt{Internal resistive force}}{\texttt{Area}}[/tex]
[tex]\sigma =\frac{F}{A}[/tex]
So, so stress distributed over an area is best described as internal resistive force.
Option D is the correct answer.
