Answer:
Realistic
Explanation:
The  acronym "SMART" stands for Specific. Measurable, Achievable, Realistic and Timely. These are criteria that  goal setting should adhere to, to ensure that the goal is achieved.
The criteria Realistic in "SMART"  emphasizes that a goal that is been set should  be realistic and  achievable  given the available resources and time.
The goal " I will triple sales in my territory by the end of the next fiscal year." is lacking the criteria of been realistic because it doesn't seem achievable within a fiscal year.
