Verified step by step guidance

Step 1: Understand the context of the question. Plasma proteins are essential components of blood and serve various functions such as maintaining osmotic pressure, immune responses, and blood clotting.

Step 2: Recall the three major types of plasma proteins. These are globulins, fibrinogens, and albumins. Albumins are the most abundant plasma proteins and play a key role in maintaining osmotic pressure and transporting substances.

Step 3: Eliminate incorrect options based on their functions and locations. Elastins, keratins, and collagens are structural proteins found in connective tissues, not plasma.

Step 4: Confirm that albumins are the correct answer by reviewing their role in plasma. Albumins are synthesized in the liver and are crucial for maintaining blood volume and pressure.

Step 5: Finalize the answer by selecting 'albumins' as the correct choice, as it fits the description of a major plasma protein alongside globulins and fibrinogens.
