End product of B-oxidation of fatty acid is –

✅Explanation:
-Beta-oxidation is a metabolic pathway that breaks down fatty acids (long chains of hydrocarbons) into smaller molecules for energy production.
-During each cycle of beta-oxidation, two acetyl CoA molecules are produced as the primary end product.
-Acetyl CoA is a crucial intermediate molecule that fuels the citric acid cycle (Krebs cycle) in the mitochondria, where most of the ATP (cellular energy) is generated from fatty acids.

📌📌Other Options:
-(a) Pyruvic acid: This is a product of glycolysis, the breakdown of glucose in the cytoplasm.
-(b) CO2: Carbon dioxide is released as a waste product during both beta-oxidation and the citric acid cycle.

🛑Aditional Information:
-All the energy required for ‘life’ processes is obtained by oxidation of some macromolecules that we call ‘food’. 
-The release of energy through oxidation is called respiration.
-Types of respiration-
-When respiratory substrates are carbohydrates like glycogen, starch, sucrose, hexose, or fats, then respiration is known as floating respiration.
-When protein is oxidized in respiration, then respiration is known as protoplasmic respiration.
-β-oxidation is the oxidation of fatty acid.
-Oxidation of fatty acids means the breakdown of fatty acids to produce energy.
-Fatty acids are the main energy source.
-The complete oxidation of food with the use of oxygen and when entire carbon released, as CO2 is called aerobic respiration. 
-Exceptionally oxidation of proteins in legume seeds is called floating respiration.
