Explanation: The gradual dissipation of the frontal zone is called frontolysis. The process by which two air masses of different physical characteristics are brought together is Frontogensis and it leads to the formation of a temperate cyclone.

Frontogenesis and Frontolysis
Frontogenesis and frontolysis are two important concepts in meteorology that describe the formation and dissipation of weather fronts.
Frontogenesis
Frontogenesis refers to the process by which a new front is formed or an existing front intensifies. This can happen when two air masses with different temperature, humidity or density characteristics collide and are forced to rise, leading to the formation of clouds and precipitation. Frontogenesis can also occur when there is a change in wind direction or speed that creates convergence or shear in the atmosphere.
Frontolysis
Frontolysis, on the other hand, refers to the process by which a front weakens or dissipates. This can happen when the two air masses that were creating the front begin to mix and lose their distinct characteristics, leading to a gradual decrease in temperature and pressure gradients. Frontolysis can also occur when the wind direction or speed changes in a way that creates divergence or a decrease in shear.
Identification of Statements
Statement (i) is incorrect because frontogenesis refers to the gradual formation or intensification of a front, not its dissipation.
Statement (ii) is incorrect because frontolysis refers to the gradual weakening or dissipation of a front, not the process by which two air masses are brought together.
Therefore, the correct answer is (d) None.
