It is the minimum anode current value required to maintain the conduction of an SCR even though the gate signal is removed. It is a very important parameter when employing an SCR in any circuit.

Explanation:
An SCR (Silicon Controlled Rectifier) is a semiconductor device that can be turned on and off by a small signal at its gate terminal. Once the SCR is turned on, it remains conducting until the anode current falls below a certain level. The value of this current is called the holding current.
When the gate signal is removed, the SCR can still remain conducting due to the presence of a certain amount of current flowing through it. This current value is called the latching current. The latching current is the minimum anode current required to maintain the SCR in the conducting state after the gate signal is removed.
Therefore, the correct answer is option B, i.e., latching current. The latching current is an important parameter of SCR as it determines the minimum current required to keep the SCR conducting even after the gate signal is removed.
Summary:
• An SCR is a semiconductor device that can be turned on and off by a small signal at its gate terminal.
• The holding current is the minimum anode current required to keep the SCR conducting.
• The latching current is the minimum anode current required to maintain the SCR in the conducting state after the gate signal is removed.
• The latching current is an important parameter of SCR as it determines the minimum current required to keep the SCR conducting even after the gate signal is removed.

Its because when the anode current reaches latching current,the reverse biased and depletion region on j2 of SCR no longer exist,therefore SCR 'll continue to conduct even if Gate pulses is remove
