Tempering is done to reduce the residual stress. Cyniding is the hardening process which increases surface hardness to great extent.

Since the question says hardened steel, so the answer is tempering.

Answer is anneling.

So annealing is the process to improve ductility, relieve the residual stresses H annealing < H tempering so we can say that annealing process is the softening process by which we can achieve more ductile material than tempering.

The answer should be Annealing.
In tempering hard steel is converted to hard steel at nearly 200 to 300 degree C. Tempering is used to remove the brittleness.

Tempering is the process that is done after hardening process. That soften the harden steel.

Annealing is the right one.

What about annealing?
Sagar Gojiya said:

Tempering is a heat-treatment process consisting of reheating the hardened steel to a temperature below 400°C, followed by cooling. Steel in its hardened condition is generally too brittle to be used for certain functions. Therefore, it is tempered.

After the hardening of steel is completed that hardened steel is softened by Tempering but normally steel is soften by the annealing process of heat treatment.
Here the answer will be tempering as it asks hardened steel is softened by the process.
