Q1. Given below are two statements: Statement (I): Blood transfusion is a method in which blood or blood products are transferred from the circulatory system of one person to another. Statement (II): The first blood transfusion was carried out by Karl Landsteiner. In light of the above statements, choose the most appropriate answer from the options given below:
Explanation
Blood transfusion does mean transferring blood or blood components from one person into another person's circulatory system, so the first statement is correct. The second statement is not correct because Karl Landsteiner is known for discovering the ABO blood group system, not for carrying out the first blood transfusion. Early transfusion experiments are associated with physicians such as Richard Lower and Jean-Baptiste Denis. Since one statement defines the process correctly and the other wrongly attributes the first transfusion to Landsteiner, the correct relationship is that the first statement is true and the second is false.
