Which of the following forces is/are fundamental in nature? 1. Gravitational force 2. Electromagnetic forces 3. Strong and weak nuclear forces Select the correct answer using the code given below:

In physics, there are four fundamental forces that govern all interactions in the universe. Option D is correct as it includes all of them:

• Gravitational Force: A universal attractive force acting between any two objects with mass. It is the weakest of the four but has an infinite range.
• Electromagnetic Force: Acts between electrically charged particles. It governs atomic structures, chemical bonds, and all magnetic phenomena.
• Strong Nuclear Force: The strongest of the four forces, it binds protons and neutrons together inside the atomic nucleus. It operates only at very short ranges.
• Weak Nuclear Force: This force is responsible for certain types of radioactive decay, such as beta decay, and is crucial for nuclear fusion processes in stars.

These forces are termed 'fundamental' because they cannot be explained by or reduced to any other more basic interactions.
