Suppose the class MyClass does not explicitly define a copy constructor. Assuming a is an object of MyClass, what is the effect of the following line of code? MyClass b = a; %3D O A shallow copy of a's data members will be given to b. O A deep copy of a's data members will be given to b. O The data members of b will be left uninitialized O The data members of b will be default initialized (to 0, false, nullptr, etc.) O That line of code would cause a syntax error.
