The correct answer is D, as all three statements are correct characteristics of contact forces.

– Contact forces are forces that arise when two objects are in physical contact with each other. Examples include normal force, friction, tension, and air resistance. Statement 1 accurately describes this.
– Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. All forces in nature, including contact forces, obey this law. For instance, if object A exerts a contact force on object B, then object B simultaneously exerts an equal and opposite contact force on object A. Statement 2 is correct.
– Contact forces can exist between solids, between a solid and a fluid (liquid or gas), or between different fluids. For example, buoyancy and drag force are contact forces between a solid and a fluid, or within a fluid. Statement 3 is correct.

Forces are broadly classified into contact forces and non-contact forces (like gravitational, electromagnetic, and nuclear forces) which act over a distance. The statements correctly describe the nature and properties of contact forces.
