Anybody tell me why E-MOSFET is "OFF" device?

May be due to some threshold voltage or high input impedance.

Zero input implies zero drain current but in JFETs and E-MOSFETs zero gate voltage implies '0' drain current. And one more thing Transistor also off the device.

Bjt is normally off state.
Fet is normally on state reason is without vgs and vds. Now also current flow into the device.

Transister and jfets are having some leakage currents so those two are in on condition.
D-mosfet always on condition. Emosfet does not having leakage cirrent, usually in of state till apply any vgs.

Normally the E-MOSFET is off till a Vgs is applied hence called an off-device unlike the D-MOSFET which has leakage current, Idss (not maximum) when Vgs is zero.

Enhancement MOSFET does not have natural channel so at VGS=0 it is in OFF state no current flow occurs.
