Experts can you tell me which option is correct 
Organisations having plans of expansion and diversification must adapt

1. Functional structure
2. Divisional structure
3. Both (a) and (b)
4. None of the above

Dear Student
1. Functional structure
Functional structure will be the best option if organisation is planning to expand and diversify. Because in this type of structure workers are organised on the basis  of specific skills and knowledge possessed by them thus giving advantage of specialisation to organisation.
