Final Answer:
The given statement" Design patterns are recommended to be used in complex applications but not necessarily" is True.
Thus correct option is a. true
Step-by-step explanation:
Design patterns are indeed recommended for use in complex applications. They provide proven solutions to recurring design problems, offering a structured approach to development. In complex systems, these patterns enhance maintainability, scalability, and code readability, aiding in managing intricate relationships between components.
Design patterns encapsulate best practices, reducing errors and promoting robustness within intricate systems. They offer a common language for developers, streamlining communication and facilitating collaboration among team members. However, for simpler applications, the overhead of implementing design patterns might outweigh their benefits, making them less necessary in those contexts.
Thus correct option is a. true
