The process that happens at the core of the Sun is called nuclear fusion. Here's a step-by-step explanation:

1. The Sun's core is extremely hot and dense. The temperature is estimated to be around 15 million degrees Celsius (27 million degrees Fahrenheit). The pressure is also incredibly high due to the gravitational force of the Sun's mass.

2. Under these conditions, hydrogen atoms in the core of the Sun move so fast that they collide with each other with a lot of force.

3. When these hydrogen atoms collide, they can overcome their natural repulsion (because they are both positively charged). This allows them to come close enough for the strong nuclear force to bind them together.

4. When two hydrogen atoms fuse together, they form a heavier atom, helium. This process is called nuclear fusion.

5. The fusion of hydrogen into helium is not a 'perfect' process. The helium atom is slightly lighter than the two hydrogen atoms that created it. The 'missing' mass is converted into energy, according to Einstein's equation E=mc^2.

6. This energy is then released in the form of light and heat, which is what we see and feel as sunlight.

So, the correct answer to your question is Fusion.
