Which of the following can be included in the inner buffer zone of Methyl Bromide if permission is obtained?

The inner buffer zone of Methyl Bromide can include adjoining property if permission is obtained because this option allows for some flexibility in land use depending on agreements made between landowners and regulatory authorities. Adjoining properties may already have existing structures or uses that could be considered in the context of pesticide application, allowing for a nuanced approach to buffer zone regulations.

For the other options, undeveloped land would generally be kept free from such chemicals to maintain ecological integrity, public parks are often off-limits due to the importance of public safety and recreational use, and schools similarly prioritize the health and safety of students and staff, making them less likely to receive permission for the use of such chemicals in close proximity. Each of these alternative choices involves considerations of public health, safety, and environmental impact, which typically preclude their inclusion in such zones without stringent oversight.
