Which options represent examples of activity/input objectives?

Activity or input objectives focus on the specific actions or processes carried out to achieve a desired outcome in public health initiatives. These objectives outline what will be done, the resources that will be utilized, or how activities will unfold to support the overall goals of a project.

In the context of the given choices, canvassing seeds and seedlings, as well as repacking and procuring seedlings, are both direct actions taken in a project setting. These are clear examples of input activities as they denote specific tasks that will lead to the eventual distribution of seedlings to families. Both of these tasks are foundational steps in ensuring that the necessary resources are available for distribution, which is crucial for supporting the families involved.

By selecting both actions a and c, the answer correctly identifies several crucial activities that contribute to the project's execution, highlighting the importance of planning and preparation in effective public health interventions. This demonstrates a comprehensive approach to outlining the steps necessary to achieve the intended public health outcomes.
