c. Memos are a highly formal type of workplace correspondence.

b. Memos are commonly written to people within your own organization.

Explanation:

Memos are the moderately formal means of communication that is used within the same organisation. It is also a formal document that is used within the same organization.

Memos are formal but not highly formal. They are used as a form of relaying short messages, usually a page or so.
