The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the presence of clotting factors in non-mammals, specifically mentioning that they do not possess platelets. 2. **Identifying Key Terms**: - **Platelets**: These are small cell fragments in mammals that play a crucial role in blood clotting. - **Thrombocytes**: These are the equivalent of platelets in non-mammals and are nucleated cells. 3. **Analyzing the Options**: - **Nucleated cells called thrombocytes**: This option refers to the cells in non-mammals that perform a similar function to platelets. - **RBC (Red Blood Cells)**: These cells are primarily responsible for oxygen transport and do not play a direct role in clotting. - **WBC (White Blood Cells)**: These cells are involved in the immune response and do not function in clotting. - **Plasma**: This is the liquid component of blood that carries cells and proteins but does not contain clotting factors in the same way that thrombocytes do. 4. **Conclusion**: Since non-mammals possess thrombocytes, which are nucleated cells that serve a similar function to platelets in mammals, the correct answer is "nucleated cells called thrombocytes". 5. **Final Answer**: The non-mammals possess clotting factors in nucleated cells called thrombocytes. ---

Consider the following four statements and select the correct option stating which ones are true (T) and which ones are false (F) ? (i) Proteins contribute 6-8 of the blood plasma (ii) Plasma contains very high amount of minerals (iii) Plasma without the clotting factors is called serum (iv) Glucose, amino acids, lipids, etc, are also present in the plasma as they are always in transit in the body.

Assertion: Platelets play an important role in blood clotting. Reason: In the blood oozing from an injury, the platelets disintegrate and release thromboplasm that initiates clotting.
