Which of the following are valid relative references?

Valid relative references are expressions that relate to the context in which they are used, allowing them to be dynamically resolved based on the current object or the hierarchical structure of objects in a system.

The term "MyEngine" refers to a specific component and can be interpreted in the context of a parent object or the current object where it is referenced. Similarly, "MyArea" can denote a specific defined region within the context and is noted as a relative reference to whatever current or parent object it uses.

"Me" is a special keyword often used in programming and scripting that refers to the current object itself, making it an inherently valid relative reference as it directly points to the object currently in context.

Therefore, all these references—"MyEngine," "MyArea," and "Me"—are indeed valid relative references as they properly reference objects and components based on the hierarchical structure or the current context in which they are called.
