For this case we have the following expression:
¡ ____ usted la página 15!
What we should do is choose the correct word to fill in the blank.
We know that we are referring to only one person.
Therefore, the order that we are going to give must be in the singular.
So, the word we are looking for is:
Lea
The complete sentence in Spanish is:
¡ Lea usted la página 15!
Answer:
c. lea
