Step 1: Understand the question.
The question asks which department of a newspaper does the creative work, such as ideas, writing and presentation.
Step 2: Recall the structure.
A newspaper organisation has editorial, marketing or advertising, circulation or distribution, production or technical and administration departments.
Step 3: Check option 1, Marketing.
The marketing department sells advertising space and promotes the paper. It is the business side, so it is not the creative organ.
Step 4: Check option 2, Distribution.
The distribution department moves printed copies to agents and readers. It is about logistics, so it is wrong.
Step 5: Check option 3, Editorial.
The editorial department generates ideas, gathers and writes news, edits it and decides the content. This is the creative work, so option 3 is right.
Step 6: Check option 4, Technical.
The technical department handles printing machines and production. It carries out the work but does not create content. So it is wrong.
Final Answer:
The editorial department is the creative organ. This is option 3.
\[ \boxed{\text{Editorial (Option 3)}} \]
