Question
The image depicts a ring and barrier diagram used to illustrate traffic signal phases at an intersection. It includes multiple lanes and directions of movement.

**Diagram Explanation:**
- The diagram is divided into two parts labeled as Ring 1 and Ring 2. Each ring contains two blocks.
- Each block is further divided, showing various traffic movements along two streets: Major Street and Minor Street.
- Movements are indicated by arrows:
  - Right arrows indicate permitted movement.
  - Solid arrows indicate protected movement.
  - Dashed arrows represent pedestrian movement.
- Each section is marked with a phase number (Φ), from Φ1 to Φ6.

**Legend:**
- Φ = Phase Number
- Dashed line arrows = Permitted Movement
- Solid line arrows = Protected Movement
- Pedestrian symbols = Pedestrian Movement

**Question:**
"In this ring and barrier diagram, which phase pairs constitute a concurrency group?"

Options:
- ○ Phase pair containing phases 1 and 2 & phase pair containing phases 3 and 4
- ○ Phase pair containing phase 1 and phase 5 & phase pair containing phases 2 and 6
- ○ Phase pair containing phase 1 and phase 2 & phase pair containing phases 5 and 6
- ○ Phase pair containing phases 5 and 6 & phase pair containing phases 3 and 4
