What is a significant reason for overloading new and delete?

To change the object's type
To modify objects' values
Efficiency in memory allocation
To use malloc and free instead

The correct answer is: Efficiency in memory allocation

When creating an object, the new operator allocates memory for that object in the heap and the delete operator deallocates that memory when the object is no longer needed. Overloading these operators allows for more control over how and where the memory is allocated and deallocated. While options A and B may seem to be relevant to the creation of an object, they actually do not have much to do with new and delete operations. Option D refers to manual memory allocation, which is not as efficient as using new and delete and can lead to memory leaks. Therefore, the most significant reason for overloading new and delete is the efficiency in memory allocation.
