Explanation

Microservices are decoupled (B) - each service runs independently with its own process and data, communicating via APIs - and they are specifically designed to create modular applications (D), where each module handles a distinct business capability that can be developed, deployed, and scaled independently.

Why the distractors are wrong:

• A is the opposite of true - independent scaling per service is one of microservices' core advantages over monoliths.
• C describes a monolithic architecture; tight coupling is what microservices were designed to avoid.
• E is wrong because microservices are decentrally managed - each service owns its own data and logic, unlike SOA or monoliths with central governance.

Memory tip: Think of microservices as a set of LEGO bricks - each brick is a separate, independent module (D) that snaps on/off without affecting the others (B). If they were centrally managed or tightly coupled, they'd be one solid block - that's a monolith.
