Bookmark is a mechanism which enables the activity to wait for the input without interrupting the workflow thread. When the activity signals that it is waiting for input from the user, it can create the bookmark. Bookmark is created by using a BookmarkOptions class, which provides bookmark types which are as follows:

MultipleResume – It refers to the bookmark which we can resume multiple times.

None – It represents the bookmark which could be resumed exactly once. This is a default bookmark type.

NonBlocking – It refers to the bookmark which does not block functioning of a workflow.
