Answer

Answer:

C. strong and weak

Explanation:

Step1: Understand the forces

The four fundamental forces are gravitational, electromagnetic, strong, and weak.

Step2: Analyze the scale

Gravitational and electromagnetic forces act on macroscopic - scale objects and can be observed in daily - life phenomena.

Step3: Identify sub - atomic forces

The strong and weak forces act on sub - atomic particles (objects not visible to the unaided eye). The strong force holds the nucleus of an atom together, and the weak force is involved in radioactive decay and certain nuclear reactions.
