The electromagnetic latching relay:
A) is used to lock in a condition.
B) uses a latch coil to set and hold the relay in the latched position.
C) uses an unlatch coil to disengage the mechanical latch.
D) all of these.
Electromagnetic Latching Relay
A type of relay that maintains its state after being actuated, using a permanent magnet to hold the armature in position until it is reset.
Latch Coil
A coil in a relay or electrical circuit that, once energized, maintains its state until it is specifically reset, allowing it to function as a memory element in a control system.
Unlatch Coil
An instruction or action that interrupts the current flow to a coil, allowing a relay or similar device to return to its de-energized state.

Final Answer :
D
Explanation :
The electromagnetic latching relay is used to lock in a condition and uses both a latch coil to set and hold the relay in the latched position, as well as an unlatch coil to disengage the mechanical latch. Therefore, all of these options are correct.
