Explanation:

Human blood consists of red blood corpuscles (RBCs), which contain antigens (proteins) on their surfaces determining blood type and giving it its red color. The serum, a straw-colored liquid after removing blood cells, contains antibodies crucial for blood classification. The ABO blood group system classifies blood based on the presence or absence of A and B antigens on Red Blood Cells (RBCs) and antibodies in the plasma. Hence, statement 1 is correct.

The ABO blood group system is used to match blood types for transfusions. People with type O blood are called universal donors because they can donate blood to anyone, while people with type AB blood are called universal recipients because they can receive blood from anyone. People with type A or B blood can receive matching blood or type O blood. Hence, statement 2 is correct.

Explanation:

The Supreme Court ruled that states cannot alter the Scheduled Caste list under Article 341 of the Constitution, quashing Bihar's 2015 notification categorizing the Tanti-Tantwa community as Scheduled Caste. Article 341(1) of the Indian Constitution grants the President the power to notify which castes are categorized as Scheduled Castes. Hence, statement I is correct.

Article 341(2) assigns the Parliament, not state legislatures, the authority to make changes to the Scheduled Castes and Scheduled Tribes lists, which requires a constitutional amendment.

Only proposals that have been agreed upon by both the Registrar General of India and the National Commission for Scheduled Castes are introduced as a Bill in Parliament. Hence, statement II is correct.

Here, statements I and II both are correct and statement II is not the correct explanation for statement I. Hence, option (b) is correct.
