. web. today’s date.
organization
publication date
author’s name

Explanation:

The dropdown is in a citation context for a USDA (an organization) source. The "Organization" option is appropriate here as USDA is the organization responsible for the source, and the other options (Publication date, Author’s name) don't fit as the source is from an organization without a single author in this context and the date is already handled as [Today’s Date] separately.

Answer:

Organization
