A. 20%
B. 70%
C. 10%
D. 50%

Answer

To determine the percentage of lymphoid tissue in the human body that is constituted by MALT (Mucosal Associated Lymphoid Tissue), we can follow these steps:

### Step-by-Step Solution:

1. **Understand MALT**: Recognize that MALT stands for Mucosal Associated Lymphoid Tissue. It is a type of lymphoid tissue associated with mucosal surfaces in the body.

2. **Identify the Major Tracts**: MALT is found in the lining of various tracts in the body, primarily:
- The digestive tract
- The respiratory tract
- The urogenital tract

3. **Determine the Composition of Lymphoid Tissue**: It is important to note that MALT constitutes a significant portion of the total lymphoid tissue in the human body.

4. **Percentage of MALT**: According to the information provided, MALT constitutes approximately 50% of the total lymphoid tissue in the human body.

5. **Final Answer**: Therefore, the answer to the question is that MALT constitutes about **50%** of the lymphoid tissue in the human body.
