Please provide detailed explanation, thank you.

Suppose a consumer's indirect utility function is V(Px, Py, I) = I(-) 1/3 2/3 3 Py . The marshallian demand functions for good x is: O a. gx(Px, Py, 1 ) = 3px O b. gx (Px, Py, I) = 3(3)" 4/3 2 . 2/3 3 Py C. gx (Px, Py, D) = ; (3) (32)2 O d. gx(Px, Py, I ) = 9px
