Let's analyze the statements about blood plasma proteins:
Statement i: "Decrease in their level causes excessive absorption of water from tissues into blood."
- This statement is incorrect. A decrease in the level of blood plasma proteins would actually result in a decrease in osmotic pressure, leading to less water being drawn from tissues into the blood. Instead, it would cause water to accumulate in the tissues, leading to edema.
Statement ii: "They maintain osmotic pressure."
- This statement is correct. Blood plasma proteins, especially albumin, play a crucial role in maintaining the osmotic pressure of the blood.
Therefore, the correct option is:
3. Statement i) is wrong and ii) is correct.

Blood Plasma Proteins: Importance and Functions
Blood plasma proteins are a crucial component of the blood that plays several essential functions in the human body. The major functions of blood plasma proteins include:
Maintaining Osmotic Pressure
Blood plasma proteins help in maintaining osmotic pressure, which is responsible for controlling the movement of fluids and nutrients in and out of the cells. These proteins are responsible for creating a balance between the fluid inside and outside the cells.
Transportation of Nutrients and Molecules
Blood plasma proteins are responsible for the transportation of various nutrients, hormones, and other vital molecules throughout the body. They bind to these molecules and carry them to different parts of the body where they are needed.
Immune Defense Mechanism
Blood plasma proteins act as the first line of defense against foreign invaders, such as bacteria and viruses. These proteins help in identifying and neutralizing the foreign antigens and pathogens in the bloodstream.
Excessive Absorption of Water from Tissues into Blood
Decreased levels of blood plasma proteins can lead to excessive absorption of water from the tissues into the blood, which can lead to edema or fluid accumulation in the tissues. This occurs because the osmotic pressure is not maintained, and the fluid moves from low to high concentration areas.
Conclusion:
In conclusion, blood plasma proteins perform a wide array of important functions. They help in maintaining osmotic pressure, transporting nutrients and molecules, and act as the first line of defense against foreign invaders. A decreased level of these proteins can lead to edema or fluid accumulation in the tissues due to excessive absorption of water from the tissues into the blood.

Blood plasma proteins maintain the blood osmolarity and a decrease in their level causes causes excess water (plasma) to be absorbed from the blood in the tissues leading to swelling of the tissues. (popularly known as edema)
