What is the behavior of a const reference in C++ when binding to a temporary object?

It extends the lifetime of the temporary object to the lifetime of the reference
It creates a copy of the temporary on the stack
It immediately destroys the temporary object
It converts the temporary into a dynamic object

The correct answer is: It extends the lifetime of the temporary object to the lifetime of the reference

A const reference in C++ extends the lifetime of the temporary object it is bound to, ensuring that the object remains valid for the duration of the reference. The other options are incorrect because creating a copy on the stack would not maintain the original object, immediately destroying the temporary is not the behavior of a reference, and converting the temporary into a dynamic object would not extend its lifetime to the reference.
