This sentence presents two design quality concepts for an ADT or module, each of which has a best practice pairing.
For the first blank, we must choose between high and low cohesion. High cohesion means the elements inside a module are strongly related and focused on a single task or closely related tasks, which generally improves maintainability, readability, and reusability. Low cohesion would imply a scattered, unfocused module, making it harder to understand and modify. Therefore, the desirable choice here is high cohesion.
Moving to the second blank, the pairings involve cohesion and coupling. Coupling refers to how dependent a module is on other modules. Low coupling is desirable because it reduces interdependencies, making modules easier to modify, test, and reuse without ripple effects. High coupling would mean heavy interdependencies, increasing fragility and maintenance burden. Thus, the desirable choice for this blank is low coupling.
Putting the selections together, the best-combined statement is: high cohesion and low coupling.
If you imagine alternative combinations, such as low cohesion or high coupling, they would imply a poorly structured module with scattered responsibilities or strong inter-module dependencies, which is contrary to good software engineering practice. In contrast, the recommended pairings—high cohesion and low coupling—align with the classic goals of modular design and information hiding.
