A fusion reaction consists of combining four protons into an `alpha`–particle. The mass of `alpha`–particle is 4.002603u and that of proton is 1.007825u, mass of electron is 0.00054466u.

Explanation

To solve the problem, we need to analyze the fusion reaction of four protons combining to form an alpha particle, which consists of two protons and two neutrons. We will calculate the mass defect and the energy released in the reaction.

### Step-by-Step Solution:

1. **Identify the Masses**:
- Mass of one proton (\(m_p\)) = 1.007825 u
- Mass of the alpha particle (\(m_{\alpha}\)) = 4.002603 u
- Mass of one electron (\(m_e\)) = 0.00054466 u
