B. Electrons – proton attraction
C. Proton – neutron attraction
D. Electron – neutron attraction

Answer

To solve the question, "A nuclear fusion process is ordinarily not possible because of," we can break it down into a step-by-step explanation:

### Step 1: Understanding Nuclear Fusion
Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy in the process. This is the same process that powers the sun and other stars.

### Step 2: Identifying the Challenge
For nuclear fusion to occur, the two nuclei must come very close to each other. However, atomic nuclei are composed of protons and neutrons. Protons carry a positive charge, and like charges repel each other.

### Step 3: The Role of Electrostatic Repulsion
When two positively charged protons approach each other, they experience a strong electrostatic repulsion due to their like charges. This repulsion creates a barrier that makes it difficult for the nuclei to come close enough for the strong nuclear force (which is attractive) to take effect.

### Step 4: Overcoming the Repulsion
To achieve fusion, the kinetic energy of the colliding nuclei must be high enough to overcome this electrostatic repulsion. This typically requires extremely high temperatures and pressures, such as those found in the cores of stars.

### Step 5: Conclusion
Thus, the reason why nuclear fusion is ordinarily not possible is primarily due to the electrostatic repulsion between the positively charged protons in the nuclei. This repulsion prevents the nuclei from getting close enough to fuse under normal conditions.

### Final Answer
A nuclear fusion process is ordinarily not possible because of the proton-proton repulsion.
