Question

Match List - I with List - II.

List - I	List - II
A. Iron	I. Cardiomyopathy
B. Copper	II. Pernicious Anemia
C. Cobalt	III. Menke's disease
D. Selenium	IV. Microcytic anemia

Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I \
• B. A-IV, B-II, C-III, D-I \
• C. A-I, B-IV, C-II, D-III \
• D. A-II, B-III, C-I, D-IV

Hint:

Iron deficiency is directly tied to microcytic anemia, while copper transport is disrupted in Menke's disease.

Answer 1

The Correct Option is A

Step 1: Concept Trace elements and essential minerals act as vital inorganic cofactors for numerous metabolic enzymes and structural physiological configurations. Deficiency states display unique clinical features depending on the biological processes disrupted.

Step 2: Meaning * Microcytic anemia: Production of abnormally small red blood cells. * Menke's disease: An X-linked recessive disorder impairing systemic copper absorption and transport. * Pernicious anemia: Macrocytic condition related to intrinsic factor or Vitamin $\text{B}_{12}$ metabolic pathways. * Cardiomyopathy: Disease damaging heart muscle tissues.

Step 3: Analysis * Iron (A) is the central element of heme; its deficiency prevents proper hemoglobin synthesis, resulting in microcytic hypochromic anemia $\rightarrow$ (A-IV). * Copper (B) metabolism is natively disrupted in Menke's disease due to mutations in the ATP7A copper-transporting ATPase $\rightarrow$ (B-III). * Cobalt (C) constitutes the core metal core of cobalamin (Vitamin $\text{B}_{12}$); its metabolic deficiency paths link directly to pernicious anemia $\rightarrow$ (C-II). * Selenium (D) deficiency causes Keshan disease, a severe, fatal condition characterized by cardiomyopathy $\rightarrow$ (D-I).

Step 4: Conclusion This matching pattern reads exactly as A-IV, B-III, C-II, D-I, corresponding to option A. Final Answer: (A)
