Software Engineering - Fundamentals

ASplit classes to have single responsibilities, depend on interfaces, and keep modules open for extension

BWrite one large class with many functions, tightly couple modules, and modify existing code often

CAvoid interfaces, repeat code for clarity, and keep all modules closed for extension

DIgnore dependencies, write complex functions, and add features without planning

Step-by-Step Solution

Solution:

Step 1: Recall SOLID principles
SOLID promotes single responsibility, dependency inversion, open/closed, and other good design practices.
Step 2: Match actions to principles
Splitting classes, using interfaces, and allowing extension without modification align with SOLID.
Final Answer:
Split classes to have single responsibilities, depend on interfaces, and keep modules open for extension -> Option A
Quick Check:
SOLID = single responsibility + interfaces + open/closed [OK]

Quick Trick: SOLID means small, flexible, and loosely coupled code [OK]

Common Mistakes:

Choosing large classes
Ignoring interfaces
Modifying code instead of extending
