Best answer

Correct option is (a) Code Duplication

For explanation: Duplication is one of the great evils in code. Take a look at the instances of repetition in your system. Perhaps they belong together. If you change something fundamental about one routine, will the similar routines need amendment? If this is the case, they probably belong in the same class.
