B. All components of blood except RBCs and some proteins
C. RBCs, WBCs and plasma
D. RBCs proteins and platelets

Answer

To determine which statement is true for lymph, we will analyze each of the provided options based on our understanding of lymph and its composition.

1. **Understanding Lymph:**
- Lymph is a colorless fluid that is derived from blood plasma. It circulates through the lymphatic system and is important for immune function and fluid balance in the body.

2. **Analyzing the Options:**
- **Option 1:** "All components of blood except WBCs and serum."
- This statement is incorrect because lymph contains a significant number of white blood cells (WBCs), which are crucial for immune responses.

- **Option 2:** "All components of blood except RBCs and some proteins."
- This statement is correct. Lymph contains various components of blood plasma, but it does not contain red blood cells (RBCs) and has fewer proteins compared to blood plasma.

- **Option 3:** "Red blood cells, WBCs, and plasma."
- This statement is incorrect because lymph does not contain red blood cells. It does contain white blood cells, but not in the same concentration as blood.

- **Option 4:** "RBCs, proteins, and platelets."
- This statement is also incorrect because lymph does not contain red blood cells or platelets, which are components of blood.

3. **Conclusion:**
- The correct answer is **Option 2**: "All components of blood except RBCs and some proteins."
