Correct answer: A

  1. We check each statement one by one.

  2. Statement (A): "Enzymes are biocatalysts."

    • This is correct.
    • Enzymes are biological catalysts that speed up biochemical reactions.
  3. Statement (B): "Enzymes are non-specific and can catalyse different kinds of reactions."

    • This is incorrect.
    • Enzymes are generally highly specific in nature. They usually act on a particular substrate or a particular type of reaction.
  4. Statement (C): "Most enzymes are globular proteins."

    • This is correct.
    • In standard biomolecules theory, most enzymes are globular proteins.
  5. Statement (D): "Enzyme oxidase catalyses the hydrolysis of maltose into glucose."

    • This is incorrect.
    • Hydrolysis of maltose into glucose is catalysed by maltase, not oxidase.
    • Oxidases are enzymes involved in oxidation reactions, not hydrolysis of maltose.
  6. Therefore, the incorrect statements are: (B) and (D)\boxed{(B) \text{ and } (D)}(B) and (D)​

  7. Matching with options:

    • Option A = (B)(B)(B) and (D)(D)(D)

Hence, the correct answer is: A\boxed{\text{A}}A​

  1. Comparison with stored correct answer:
    • Stored correct answer = A
    • Our derived answer = A
    • So, they agree.
