Options
Answer: (4) 2 and 4
Explanation:
Statement 1 is partially correct but overstated: Convalescent plasma (from COVID-recovered patients) contains antibodies against coronavirus — however, not all blood plasma contains significant COVID antibodies; only plasma from recovered patients does. Statement 2 is correct: Blood plasma is a pale yellow (straw-coloured) liquid that makes up approximately 55% of blood volume, containing water, proteins (albumin, fibrinogen, immunoglobulins), electrolytes, and nutrients. Statement 3 is incorrect: Blood plasma does NOT contain haemoglobin — haemoglobin is found inside red blood cells (erythrocytes), not in plasma. Statement 4 is correct in context: The question refers to the COVID-19 convalescent plasma therapy where recovered patients donate plasma to help active patients — any recovered donor (with matching blood type considerations) can donate. Hence statements 2 and 4 are correct.
