Best answer
The correct option is (a) True

The explanation: In heat treatment of metals, first stage involves heating of metals in which metal is uniformly heated with appropriate heating rate. The heating rate of metal mainly depends on the thermal conductivity of metal and also depends on the metal condition like its size and cross-section.
