Which type of coupling is considered the most desirable?Options :Data CouplingControl CouplingStamp CouplingContent Coupling

The most desirable type of coupling is Data Coupling.

Here's why:

1. Data Coupling: This is when two modules interact by only passing data (as parameters) from one to another. This is the simplest and most desirable type of coupling because it doesn't involve any knowledge about the inner workings of the modules.

2. Control Coupling: This is when one module controls the flow of another by passing it information on what to do (e.g., passing a control flag).

3. Stamp Coupling: This is when modules share a data structure and use only a part of it (i.e., they have a 'stamp' of data that they work with).

4. Content Coupling: This is when one module modifies or relies on the internal workings of another module (e.g., changing a variable in another module). This is the least desirable type of coupling because it creates a high degree of dependency between modules.

So, in terms of desirability, it would be: Data Coupling > Control Coupling > Stamp Coupling > Content Coupling.
