B. Backward chain
C. Total-task chaining
D. Reverse function training

Backward chaining

Explanation:

Since we are given the information that

Sandie learned the last two steps of the task, this is backward chaining. Backward chaining begins with the goal and then the achievement of the knowledge unlike the forward chaining that starts with knowledge.
