The Decorator [^] pattern may be appropriate but some have suggested the Strategy[^] pattern.

Here is an example of what you are trying to do - https://thispointer.com/strategy-design-pattern/[^] - be aware that your tutor will be familiar with that article.

The links at the top of this post are from .NET Design Patterns in C# and VB.NET - Gang of Four (GOF) - doFactory.com[^]. I have no affiliations with DoFactory

Thanks for your kind help. I have done some research on both the suggested patterns & looks like Decorator pattern will fit in my requirements.
