If a system uses Dependency Injection (DI) extensively but experiences runtime errors due to missing dependencies, what advanced approach can help detect these issues earlier and improve robustness?

AManually instantiate all dependencies in client code to ensure correctness.

BRely solely on runtime exception handling to catch missing dependencies.

CAvoid using interfaces and inject concrete classes directly to reduce complexity.

DUse compile-time dependency injection frameworks or static analysis tools to verify dependency graphs.

Step-by-Step Solution

Step 1: Identify the problem
Runtime errors from missing dependencies indicate lack of early validation.
Step 2: Evaluate solutions
Use compile-time dependency injection frameworks or static analysis tools to verify dependency graphs. suggests compile-time DI or static analysis, which can catch missing dependencies before runtime. Rely solely on runtime exception handling to catch missing dependencies. defers detection to runtime, which is less robust. Avoid using interfaces and inject concrete classes directly to reduce complexity. breaks DIP and reduces flexibility. Manually instantiate all dependencies in client code to ensure correctness. defeats DI benefits and increases coupling.
Final Answer:
Option D -> Option D
Quick Check:
Compile-time checks improve reliability by catching DI issues early.

Quick Trick: Use compile-time DI or static analysis to catch missing dependencies early.

Common Mistakes:

MISTAKES

Relying only on runtime exceptions
Injecting concrete classes instead of abstractions
Manual instantiation defeating DI benefits

Trap Explanation:

PITFALL

Options B, C, and D ignore early error detection or sacrifice design principles.
