What is the main problem caused by the Tight Coupling anti-pattern in system design?

AModules depend heavily on each other, making changes risky

BModules are completely independent and cannot communicate

CModules use too many interfaces to communicate

DModules are loosely connected with clear boundaries

Step-by-Step Solution

Solution:

Step 1: Define Tight Coupling
Tight coupling means modules depend heavily on each other, so changing one affects others.
Step 2: Match options to definition
Modules depend heavily on each other, making changes risky correctly describes this risk, while others describe independence or loose coupling.
Final Answer:
Modules depend heavily on each other, making changes risky -> Option A
Quick Check:
