Match List-I with List-II

List-I	List-II
(A) Consumer's equilibrium	(I) ΔY/ ΔX
(B) Slope of IC	(II) Budget line rotates to the right starting from the Y axis
(C) Px falls	(III) Consumer should move downwards to the right along the IC
(D) MRSxy > Px/Py	(IV) Optimum choice of the consumer

Choose the correct answer from the options given below:

Option 1: (A) - (IV), (B) - (I), (C) - (II), (D) - (III) -> Let's match each concept:

(A) Consumer's equilibrium matches with (IV) Optimum choice of the consumer - Consumer equilibrium occurs at the point where the consumer maximizes utility subject to budget constraint, representing the optimal consumption bundle.

(B) Slope of IC matches with (I) ΔY/ΔX - The slope of an indifference curve represents the marginal rate of substitution (MRS), which is mathematically expressed as ΔY/ΔX, showing the rate at which a consumer is willing to trade Y for X.

(C) Px falls matches with (II) Budget line rotates to the right starting from the Y axis - When the price of good X decreases, the X-intercept (M/Px) increases while the Y-intercept (M/Py) remains unchanged, causing the budget line to pivot outward from the Y-axis.

(D) MRSxy > Px/Py matches with (III) Consumer should move downwards to the right along the IC - When MRS exceeds the price ratio, the consumer values X more relative to Y than the market does, so they should consume more X and less Y (moving down-right on the IC) until MRSxy = Px/Py for equilibrium. -> correct
