Instructional/pedagogical planning operates at three nested levels: the Year Plan (a broad annual overview of the syllabus), the Unit Plan (a mid-level reorganisation of the syllabus into cohesive 'units' of logically related topics), and the Lesson Plan (a single class session). The defining purpose of forming 'units' at the Unit Planning stage is to reorganise the subject matter into a logical, connected sequence — grouping related concepts together and arranging them from simpler or prerequisite ideas to more advanced ones.

Applying this to the item: when subject matter is reorganised into units during Unit Planning, the goal is precisely to arrange the content logically — related topics are grouped and sequenced coherently so teaching proceeds in a connected order. This matches 'Organising content logically'.

• Simplifying assessment methods belongs to the separate evaluation-planning step of instructional design, not to how content is grouped into units.

• Ensuring uniform pace is a time/schedule-allocation concern addressed in the Year Plan, not the reason units are formed.

• Reducing teacher workload is, at most, an incidental effect on the teacher's preparation effort, not the defining purpose of grouping content into units.

Therefore, the primary purpose of reorganising subject matter into units during Unit Planning is to organise the content logically.
