Answer:
Instructions
Explanation:
Instruct means "direct or command someone to do something, especially as an official order."
Instructor means "a person who teaches something."
Instructions mean "a direction or order."
Instructional means "intended or used for teaching; educational."
The word choice, instructions, seems to fit the best because when you read the sentence with the word it makes the most sense and the word is the right choice here.
