Question

What does the principle of "defaults" contribute to robustness in the user interface?

a.

It allows users to explore the internal state of the system.

b.

It provides preset values and options to streamline user interactions.

c.

It ensures users have visibility into the operations performed by the system.

d.

It allows users to revise their task-action plan based on observations.

Answer: (b).It provides preset values and options to streamline user interactions. Explanation:The principle of "defaults" ensures that the user interface offers preset values and options, reducing the need for users to input every setting and improving the efficiency of interactions.
