Solution:A, C, D, & E are correct option.
Note:-The Walrasian demand function, x(p,w), is a function that specifies the demand for a good for every possible price vector, p, and wealth level, w. It has
following properties.
Weak axiom of revealed preference: For any two price -wealth situations, (p, w) and (po, wo), if p. x (po, wo) ≤ w and x(p, w) ≠ x(po, wo), then po. x(p, w) > wo.
Homogeneity of degree zero.
x(p, w) = x(αp,αw) for all α > 0.
The Walrasian demand function is equal to the derivatives of indirect utility function multiplied by correcting term that normalizes by the marginal utility
of wealth.
