Explanation:

- Procurement provisions refer to the process of purchasing goods or services, often by a government. While important, it doesn't directly support agriculture as a whole.

- Subsidized provisions would mean that financial assistance or price reductions are given. This term is specific to financial support, not a general provision.

- Adequate provisions mean that sufficient or satisfactory measures have been made. This choice broadly covers the necessary support for agriculture, including financial, physical, and policy-related support.

- Capital provisions relate to funding or resources used to create wealth, more specific to financial investments rather than overall support.
