B. If both assertin and reason are ture but reason is not the correct explanation of assertion .
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

**Step 1: Understand the Assertion**
- The assertion states that "Dielectric polarization means formation of positive and negative charges inside the dielectric."
- When a dielectric material is placed in an electric field, the electric field causes the molecules within the dielectric to become polarized. This means that the positive and negative charges within the molecules shift slightly, leading to a separation of charge. This results in the formation of induced positive and negative charges on opposite sides of the dielectric material.

**Conclusion for Step 1:**
- The assertion is **true** because dielectric polarization indeed involves the formation of positive and negative charges due to the shift of charge within the molecules of the dielectric.

**Step 2: Understand the Reason**
- The reason states that "Free electrons are formed in this process."
- In the process of dielectric polarization, the molecules do not lose or gain free electrons. Instead, the existing charges within the molecules are displaced. Free electrons are typically associated with conductive materials, where they can move freely. In dielectrics, the electrons are bound within the atoms or molecules and do not become free.

**Conclusion for Step 2:**
- The reason is **false** because dielectric polarization does not involve the formation of free electrons; it only involves the displacement of bound charges.

**Final Conclusion:**
- The assertion is true, while the reason is false. Therefore, the correct answer is that the assertion is true and the reason is not the correct explanation of the assertion.
