Match List-I with List-II and select the correct answer: List-I: (A) Law of Diminishing Returns (B) Returns to Scale (C) Marginal Product (D) Isoquant List-II: (I) Long run (II) Fixed factor (III) Change in Total Product (TP) (IV) Equal output

The point at which the total product curve begins to flatten out indicates:

Which of the following statements regarding the Cobb-Douglas Production Function Q = A Lα Kβ are correct? I. The positive constants α and β represent the output elasticities of labor and capital, respectively. II. Constant returns to scale are achieved when α + β = 1. III. The function can be expressed in logarithmic form as ln(Q) = ln(A) + α ln(L) + β ln(K). IV. The constant 'A' represents total factor productivity or technological progress.
