You are tasked with developing a theme manager that produces sets of UI widgets (e.g., sliders, dropdowns) that must maintain a uniform look and feel across the application. Which design pattern is most appropriate to ensure consistent widget families?

AAbstract Factory

BBuilder

CFactory Method

DSingleton

Step-by-Step Solution

Solution:

Step 1: Identify the need for families of related objects
The problem requires creating multiple related UI widgets that share a consistent style.
Step 2: Match pattern to requirement
Abstract Factory is designed to create families of related objects without specifying their concrete classes.
Final Answer:

Confusing Singleton as a creational pattern for single instances only

Trap Explanation:

PITFALL

Builder is for stepwise construction, not for creating families of related objects.
