Choose the most appropriate answer from the options given below :

  1. A
    A-III, B-IV, C-II, D-I
  2. B
    A-III, B-II, C-I, D-IV

Correct answer: C

  1. Recall the functions of the given enzymes

    • Invertase converts cane sugar (sucrose) into glucose and fructose.
      So it matches IV. Cane sugar into glucose (school-level shorthand).

    • Zymase converts glucose into ethanol during fermentation.
      So it matches III. Glucose into ethanol.

    • Diastase converts starch into maltose.
      So it matches I. Starch into maltose.

    • Maltase converts maltose into glucose.
      So it matches II. Maltose into glucose.

  2. Write the matching

    A→IV,B→III,C→I,D→IIA \to IV,\quad B \to III,\quad C \to I,\quad D \to IIA→IV,B→III,C→I,D→II

  3. Compare with options

    • Option A: AAA-III,BIII, BIII,B-IV,CIV, CIV,C-II,DII, DII,D-III ❌
    • Option B: AAA-III,BIII, BIII,B-II,CII, CII,C-I,DI, DI,D-IVIVIV ❌
    • Option C: AAA-IV,BIV, BIV,B-III,CIII, CIII,C-I,DI, DI,D-IIIIII ✅
    • Option D: AAA-IV,BIV, BIV,B-II,CII, CII,C-III,DIII, DIII,D-III ❌

  4. Final answer

    The correct match is: A→IV, B→III, C→I, D→II\boxed{A\to IV,\ B\to III,\ C\to I,\ D\to II}A→IV, B→III, C→I, D→II​ Hence, the correct option is C.
