An extremely easy question about NMOS

[l46kok]

Find the region of operation and drain current in an NMOS transistor.

When they say region of operation, are they asking for the type of device (enhancement-mode or depletion-mode)? or the modes of operations (Cutoff, Triode or Saturation)?

[Molecular]

The modes of operations are as you said the cutoff-region, Triode-region and the Saturation-region.
