Why are heat transfers associated with phase changes known as latent or "hidden" heats?

heat absorbed or released in a phase change is measured in kj while temperature is measured in °c.

the enthalpy of vaporization and enthalpy of condensation values for a substance add to zero.

the enthalpy change values for pure substances tend to be small.

the heat absorbed or released by a phase change does not cause a temperature change.

The best and most correct answer among the choices provided by your question is the first choice or letter A.

Heat transfers associated with phase changes known as latent or "hidden" heats because heat absorbed or released in a phase change is measured in kJ while temperature is measured in °C.
