It is true, since typical semiconductors like silicon and germanium have negative temperature coefficient which indicates that as temperature increases it's resistance decreases effectively becoming like a short.

Agree @Krushana.

I think true, because when a diode is placed at absolute zero temperature the diode will become an insulator.

Because diode has negative temperature coefficient of resistance so as temp increases the conductivity increases thereby short circuit.
