Which would be the correct way to instantiate a containerClass object in your main program?

template
class containerClass
{
public:
containerClass();
containerClass(int newMaxSize);
containerClass(const containerClass& source);
~containerClass();
T getItem();
int getCount();
int getSize();
void addItem(T item);

private:
T *container;
int maxSize, count;
};
a. containerClass myContainer;
b. containerClass myContainer;
c. containerClass myContainer;
d. containerClass myContainer

c. containerClass myContainer;
