In an n-channel JFET, what will happen at the pinch-off voltage?

• the value of VDS at which further increases in VDS will cause no further increase in ID
• the value of VGS at which further decreases in VGS will cause no further increases in ID
• the value of VDG at which further decreases in VDG will cause no further increases in ID
• the value of VDS at which further increases in VGS will cause no further increases in ID
