HELP I will mark u as BRAINLIEST

Read the letter Shontal has started writing to school leaders.
Many students think the school needs more trees, Trees are beautiful, and planting more trees would improve the appearance of our
school. The trees would help keep the building cooler during hot weather. If we had trees by the playground, students could cool off in the shade.
Planting trees between the school and the street would help block traffic noise. The trees also would provide homes for birds and other animals,
Students could learn about the trees and help take care of them
Shontal wants to add a final sentence to her letter,
Which sentence best supports Shontal's argument?
O1 We could plant many different kinds of trees
O2. We could learn which trees grow in different climates.
3. We could start planting the trees as early as next spring
