A horticulturist is choosing a seedling for a roof garden where watering is limited. The table shows measurements from four seedlings.
| Seedling | Total exposed leaf area / cm2\mathrm{cm^2}cm2 | Cuticle |
|---|---|---|
| A | 160 | thick |
| B | 85 | thick |
| C | 85 | thin |
| D | 160 | thin |
All other factors affecting water loss are the same.
Which seedling is expected to lose water at the lowest rate?
Seedling B
Seedling D
Seedling C
Seedling A
