Match List-I with List-II

List-I	List-II
(A) MPS	(I) $C/Y$
(B) MPC	(II) $\bar{C} + cY$
(C) APC	(III) $1 - c$
(D) Consumption function (C)	(IV) $\Delta C/\Delta Y$

Choose the correct answer from the options given below:

Option 1 -> MPS as C̄ + cY is incorrect; MPS = 1 - c, not the consumption function.

Option 2 -> MPS as C/Y is incorrect; that's APC, not MPS.

Option 3 -> MPS as C/Y and APC as ΔC/ΔY are both incorrect matches.

Option 4 -> Correctly matches all: MPS = 1 - c (proportion of additional income saved), MPC = ΔC/ΔY (change in consumption per unit change in income), APC = C/Y (ratio of total consumption to total income), and Consumption function = C̄ + cY (autonomous consumption plus induced consumption).

Hence, Option 4: (A) - (III), (B) - (IV), (C) - (I), (D) - (II) -> MPS (Marginal Propensity to Save) equals 1 - c where c is MPC, representing the fraction of additional income that is saved. MPC (Marginal Propensity to Consume) is ΔC/ΔY, showing how consumption changes with income. APC (Average Propensity to Consume) is C/Y, the ratio of total consumption to income. The Consumption function C = C̄ + cY shows total consumption as autonomous consumption (C̄) plus income-dependent consumption (cY). -> correct
