Aboard approved safety manual for airport security is an example of a. formal upward message b. formal downward message c. formal lateral message d. informal grapevine message

B. Formal downward message

Explanation:

In formal downward communication, messages and orders start from the upper levels of the organizational hierarchy and are directed towards lower levels, from where the response moves up the same path. In this case, the Board of directors represents the upper level, while Airport Security is the lower level receiving the message (approval of the Safety manual).

Formal upward communication is the exact opposite - the message starts at the bottom levels of the hierarchy.

Formal lateral communication refers to communication between two workers who are on the same level.

Informal grapevine communication is workplace communication in which conversations between employees and superiors do not follow any particular rules.
