For using a multimeter to identify a diode from electrical components,choose the correct statement about the diode from the following:
- AIt is a two-terminal device which conducts current in both directions.
- BIt is a two-terminal device which conducts current in one direction only.
- CIt does not conduct current and gives an initial deflection which decays to zero.
- DIt is a three-terminal device which conducts current in one direction only between the central terminal and either of the remaining two terminals.
