The forces exerted on a body during a short period are known as:

Correct option is A

The correct answer is (a) Impulse.
· In physics, impulse is defined as the change in momentum of an object when it is acted upon by a force for a short period of time.
· It is calculated as the product of the force applied and the time interval during which it acts.
· It is a vector quantity and Its SI unit is N-s or Kg-m/s.
· Pressure: Pressure is the force per unit area applied in a direction perpendicular to the surface of an object.
· Its SI unit is N/m2, also called pascal.
· It is a scalar quantity.
· Surface tension: Surface tension is the contractive tendency of the surface of a liquid that allows it to resist an external force.
· Tensile stress: Tensile stress is the stress that tends to stretch or elongate a material.
