Most of energy released in the fission is carried by

Options

A. neutrons
B. fission fragments
C. neutrons and fragments carry equally
D. positrons

Answer

To solve the question "Most of the energy released in the fission is carried by," we can break down the process of nuclear fission and identify the carriers of energy.

### Step-by-Step Solution:

1. **Understanding Nuclear Fission**:
- Nuclear fission is a process where a heavy nucleus, such as Uranium-235, splits into two smaller nuclei (fission fragments) when it absorbs a neutron.

2. **Identifying the Products of Fission**:
- When Uranium-235 undergoes fission, it typically produces two smaller nuclei, such as Barium-144 and Krypton-89, along with additional neutrons.

3. **Energy Release in Fission**:
- The fission process releases a significant amount of energy. This energy comes from the binding energy of the nucleus, which is released when the nucleus splits.

4. **Energy Carriers**:
- The energy released during fission is primarily carried away by the fission fragments (the smaller nuclei formed) and the kinetic energy of the emitted neutrons.

5. **Conclusion**:
- Among the products of fission, the fission fragments carry most of the energy released. Therefore, the correct answer to the question is that most of the energy released in fission is carried by the fission fragments.

### Final Answer:
Most of the energy released in fission is carried by **fission fragments**.
