Question 10Module A and B both rely on the same composite data structure. This is an example of what type of coupling?1 pointMedium data structure couplingMedium control coupling

This is an example of Medium data structure coupling.

Here's why:

Coupling refers to the degree to which one module (or component) of a system relies on other modules. The types of coupling, in increasing order of severity, are as follows:

1. Simple data coupling: Modules share data through, for example, parameters. Each datum is an elementary type.
2. Stamp coupling (Data-structured coupling): Modules share a composite data structure and use only a part of it, possibly different parts.
3. Control coupling: One module controlling the flow of another, by passing it information on what to do.
4. Common coupling: Two modules share the same global data (e.g., a global variable).
5. Content coupling: When one module uses the code of another module, for instance a branch.

In the case of Module A and B both relying on the same composite data structure, they are sharing a data structure and likely using different parts of it. This fits the definition of Stamp Coupling or Medium data structure coupling.
