Answer and explanation
Correct answer
C. Field injection makes unit testing more difficult.
Why
Field injection can make unit testing more difficult because it relies on reflection to set dependencies, which can lead to less clear and maintainable tests. Constructor injection, on the other hand, promotes immutability and clear dependency contracts, simplifying testing and code maintenance.
