You are most likely to experience flow if you are

A) externally motivated to perform the task.
B) completing a new task.
C) completing a task you have done repeatedly in the past.
D) intrinsically motivated for the task.

Flow is most likely to occur when the task at hand is intrinsically motivating, meaning you are doing it for the inherent satisfaction and enjoyment of the activity itself rather than external rewards like money or fame. When you are intrinsically motivated, you are more likely to become absorbed in the activity and lose track of time, leading to a state of flow.
