Given the following class definition, how would you declare an object of the class, so that the object automatically called the default constructor?

class ItemClass
{
public:
ItemClass();
ItemClass(int newSize, float newCost);
int getSize();
float getCost();
void setSize(int newSize);
void setCost(float newCost);
private:
int size;
float cost;
};
a. ItemClass() myItem;
b. ItemClass myItem(1, 0.0);
c. ItemClass myItem;
d. ItemClass myItem();
e. You can not do this

c. ItemClass myItem;
