Solution Steps

Step 1: Understanding the Question

The question asks where in the Sun the fusion of hydrogen occurs. This is a multiple-choice question with several options provided.

Step 2: Analyzing the Options

The options given are:

  1. Only near the photosphere (its visible surface layer)
  2. Only in the core
  3. Only in the layer where there is a lot of convection going on
  4. Nowhere
  5. Pretty much throughout the entire body of the Sun
Step 3: Applying Knowledge of Stellar Physics

Hydrogen fusion in the Sun occurs under conditions of extremely high temperature and pressure, which are only found in the core of the Sun. The core is the central region where the temperature reaches about 15 million degrees Celsius, and the pressure is immense, allowing nuclear fusion to occur.

Final Answer

\[ \boxed{\text{only in the core}} \]
