The correct answer is option 1
Concept:
Gate the control element in Silicon Controlled Resistor

Gate is used to trigger the device into conduction by the application of a small voltage.

By increasing the gate current, the forward break-over voltage occurs for lower values of forwarding voltage which is shown in the figure
