2. **Analyzing the Options:**
- **Option 1:** Excess production of WBC (White Blood Cells) - This describes leukocytosis, not thrombocytopenia.
- **Option 2:** Less number of platelets - This accurately describes thrombocytopenia.
- **Option 3:** Excess platelets - This condition is known as thrombocytosis, which is the opposite of thrombocytopenia.
- **Option 4:** Less production of WBC - This condition is called leukopenia, which does not relate to platelets.

3. **Identifying the Correct Answer:**
- Based on the analysis, the correct answer is **Option 2: Less number of platelets**. This is the defining characteristic of thrombocytopenia.

4. **Conclusion:**
- Thrombocytopenia is specifically defined as a condition where there is a decreased number of platelets in the blood, leading to potential bleeding issues.
