Inheritance is denoted by the colon operator and the syntax for a derived class is "class DerivedClass : public BaseClass". Therefore, the valid definition of a derived class bClass that inherits from a base class aClass is "class bClass : public aClass". Option B matches this syntax, and is therefore the correct choice. Option A has the derived class before the base class which is incorrect. Option C has the base class before the colon which is also incorrect. Option D has the derived class before the colon and does not specify public inheritance, which is also incorrect.
