What does upcasting mean?

Converting a base type to a derived type
Deleting unnecessary parts of code
Converting a derived type to its base type
Increasing variable value

The correct answer is: Converting a derived type to its base type

Upcasting is a term used in object-oriented programming, where a derived type is converted to its base type. This means that an instance of a class that inherits from a parent class can be used as an instance of the parent class. This allows for polymorphism, where a single code can be used for multiple types of objects. Option A is incorrect because it is the opposite of what upcasting means. Option B is incorrect because it is describing a different concept called dead code elimination. Option D is incorrect because it is not related to the concept of upcasting.
