Read the following statements and find out incorrect statements.
a. Blood is a loose connective tissue consisting of a fluid matrix, plasma and formed elements.
b. Plasma is a straw coloured, viscous fluid constituting nearly 90-92 precent of the blood.
c. 55 percent of plaasma is water and proteins contribute 6-8 per cent of it.
d. Fibrinogen are needed for clooting or coagulation of blood.
(e) Factors for clotting of blood are present in the plasma in an inactive from.

Options

A. a,b and c
B. b,c and d
C. c,d and e
D. a,b and e

Explanation

To solve the question of identifying the incorrect statements about blood and plasma, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement A**: "Blood is a loose connective tissue consisting of a fluid matrix, plasma and formed elements."
- **Analysis**: This statement is incorrect because blood is classified as a specialized connective tissue, not a loose connective tissue. It does consist of a fluid matrix (plasma) and formed elements (cells), but the classification as "loose connective tissue" is wrong.
- **Conclusion**: **Incorrect Statement**.

2. **Statement B**: "Plasma is a straw coloured, viscous fluid constituting nearly 90-92 percent of the blood."
- **Analysis**: This statement is also incorrect. Plasma is indeed a straw-colored, viscous fluid, but it constitutes about 55% of the blood, not 90-92%.
- **Conclusion**: **Incorrect Statement**.

3. **Statement C**: "55 percent of plasma is water and proteins contribute 6-8 percent of it."
- **Analysis**: This statement is incorrect as well. In fact, plasma is composed of approximately 90-92% water, and proteins make up about 6-8% of the plasma, not of the total blood volume.
- **Conclusion**: **Incorrect Statement**.

4. **Statement D**: "Fibrinogen are needed for clotting or coagulation of blood."
- **Analysis**: This statement is correct. Fibrinogen is a protein in plasma that is essential for blood clotting.
- **Conclusion**: **Correct Statement**.

5. **Statement E**: "Factors for clotting of blood are present in the plasma in an inactive form."
- **Analysis**: This statement is also correct. The clotting factors are indeed present in the plasma in an inactive form to prevent unnecessary clotting.
- **Conclusion**: **Correct Statement**.

### Summary of Incorrect Statements:
- The incorrect statements are A, B, and C.

### Final Answer:
The incorrect statements are A, B, and C.
