To analyze the statements:
- Statement i is correct; it describes the slow reaction rate in the absence of an enzyme.
- Statement ii is also correct; it accurately describes the function of carbonic anhydrase and its dramatic acceleration of the reaction rate.
- Statement iii is accurate; it notes that the pathway from glucose to pyruvic acid consists of ten enzyme-catalyzed reactions.
- Statement iv is incorrect; under anaerobic conditions, lactic acid is produced in skeletal muscle, not pyruvic acid.
Therefore, the correct answer, which includes statements i, ii and iii, is Option B.

Analysis of Statements
To evaluate which statements are correct, let’s break down each one:
i. Formation of H2CO3 without Enzyme
- The statement claims that in the absence of any enzyme, the formation of H2CO3 is very slow, with about 200 molecules produced in an hour.
- This statement is correct. The formation of carbonic acid (H2CO3) from carbon dioxide (CO2) and water (H2O) occurs slowly without enzymes.
ii. Role of Carbonic Anhydrase
- This statement asserts that carbonic anhydrase accelerates the reaction rate by approximately 10 million times, producing about 600,000 molecules of H2CO3 every second.
- This statement is also correct. Carbonic anhydrase is a highly efficient enzyme that dramatically increases the rate of H2CO3 formation.
iii. Metabolic Pathway from Glucose to Pyruvic Acid
- This statement indicates that the pathway involves ten enzyme-catalyzed reactions.
- This statement is correct. The glycolytic pathway, which converts glucose to pyruvate, consists of ten distinct enzymatic steps.
iv. Anaerobic Conditions in Skeletal Muscle
- This statement claims that under anaerobic conditions in skeletal muscle, pyruvic acid is formed instead of lactic acid.
- This statement is incorrect. Under anaerobic conditions, pyruvic acid is converted to lactic acid.
Conclusion
Based on the analysis, statements i, ii, and iii are correct. Therefore, the correct answer is option 'B', which includes statements i, ii, and iii.
- Correct Statements: i, ii, and iii
- Incorrect Statement: iv
