Spring Boot - Fundamentals

AThe project will not build because Gradle files are missing

BThe application will fail to compile due to missing Lombok annotations

CDatabase connections will fail due to missing JPA dependencies

DNo HTTP server will start, causing 404 errors on REST endpoints

Step-by-Step Solution

Solution:

Step 1: Understand the role of 'Spring Web'
It provides embedded web server and MVC framework needed for REST controllers.
Step 2: Consequence of omission
Without it, no embedded server starts, so REST endpoints return 404 or connection refused.
Step 3: Exclude other options
Lombok and JPA are unrelated to web server startup; Gradle files depend on build tool choice.
Final Answer:
No HTTP server will start, causing 404 errors on REST endpoints -> Option D
Quick Check:
Missing Spring Web means no embedded server [OK]

Quick Trick: No Spring Web means no embedded server for REST [OK]

Common Mistakes:

Assuming compilation errors instead of runtime issues
Confusing web dependency with database dependencies
Thinking build files are missing
