1. increasing dehydration of leaf tissues
2. decreasing dehydration of leaf tissues
3. countering the effect of declining CO2 on photosynthesis
4. reinforcing the effect of declining CO2 on photosynthesis
5. decreasing the O2 content of air next to the leaves lower than it would otherwise be
6. increasing the O2 content of air next to the leaves higher than it would otherwise be
A) 1, 3, and 5
B) 1, 3, and 6
C) 1, 4, and 5
D) 2, 3, and 6
