Central Board Of Secondary Education [CBSE] — Wrong Answer for 12th class Business Studies term 1

The correct answer for question no. 20 of question paper 066/2/4 of business studies should be option (c) to facilitate expansion and growth, as departmentalisation, the second step of organising helps in expansion of business without disturbing the operations of other departments but the answer given in the answer key is option (b) facilitate specialization which cannot be the correct answer as specialization occurs due to the division of work which comes under first step of organising that is identification and division of work. This can further be justified through chapter no 2 Principles of Management, the first principle of Henry Fayol says that division of work should be done for specialization. Please consider my request and I hope there will be some positive response
