Q.In a database application, the part that the user sees and interacts with — the forms, buttons and text boxes — is called the:

The question points to the visible, interactive part of the application — the user interface.

What the user sees and works with is the presentation layer.

The front-end (also called the presentation layer or user interface) is the part of a database application that the user sees and interacts with — its screens, forms, buttons and text boxes. Its job is to take input and show output; it does not itself store data permanently.

Option-by-option analysis:

• (a) Back-end is the hidden part that stores and manages the data (the database and DBMS) — not what the user directly works with.
• (b) Front-end is correct — the visible, interactive interface.
• (c) Driver is the software component that translates between the front-end and the database during connectivity, not the interface itself.
• (d) Result set is the set of rows returned by a SELECT query, not a part the user works with directly.

Swapping front-end and back-end. The front-end is what the user SEES (interface); the back-end is where data is STORED (database), hidden from the user.
