1. We're interested in the ratio Primrose to Pine, which is the ratio of the blue to black columns.
2. Let's calculate the ratio for all 6 zones.
- A. 3600:1000 = 3.6
- B. 1600:600 \(\approx\) 2.7
- C. 1700:600 \(\approx\) 2.8
- D. 250:1250 = 0.2
- E. 900:600 = 1.5
- F. 1400:800 \(\approx\) 1.8
3. Primrose is invasive in any zone with a ratio greater than two - A, B, and C.
4. The highest ratio can be seen in zone A, with a value of around 3.6.
5. Our answer will be: D1 - 3 and D2 - A.
