What are the names of three different types of flags?

The correct answer includes garrison, storm, and post flags, which are all specific types of flags used by military and governmental organizations.

A garrison flag is a large flag typically flown on military installations, especially on national holidays and during special occasions. It represents a display of pride and respect for the nation.

A storm flag, on the other hand, is a smaller, more durable flag that is used in inclement weather conditions. It is designed to be flown during storms or periods of high winds when a larger flag might be damaged.

The post flag is the standard size flag that is used on military posts on a daily basis, representing the installation or unit when activities take place.

Together, these flags signify different levels of display and purpose, corresponding to the conditions and contexts in which they are flown. The other options do not specify recognized flag types in this context; thus, they do not fulfill the criteria set by the question.
