This is simple explanation that depends on the depletion region, as Vgs increases, it tend to increase the depletion region. As the depletion region decreases it tends to allow less electrons flow through the channel, as the number of electrons flowing through the channel decreases then current also decreases.

The correct option is D. Because constant current region means saturation region, so as Vgs increases Id remains constant.

Yes as VGS decreases ID decreases but also when VGS increases ID remains constant so I think option D is also correct.
