consider the following code snippet: consider the following code snippet: (B (A class A{ public: A(int x){ } int foo() const { return 0; } }; main({ A obj(10); obj.foo0; } class Al public: A(int x){ } int foo() const { return 0; } }; maino A obj(10); obj.foo0; } O a. obj cannot invoke foo O b. obj can invoke foo O a. obj cannot invoke foo O b.obj can invoke foo O c. All other answers are wrong O c. All other answers are wrong O d. the code will not compile O d. the code will not compile
