Explanation:
When we declare a variable as reference type we have to initialize that variable otherwise the compiler will give error that the reference variable is not initialized.You also cannot initialize the variable Foo& with NULL value because it is a reference variable and we have to initialize it.
On the other there is no need to initialize the variable Foo * since it is a pointer it can also store NULL value.
So the answer is only Foo* can store NULL value not Foo &.
