Here is the sentence:
Jacob's physics notes were tucked in his book bag. A half-read copy of
Moby-Dick served as a coaster for a glass of cold soda. An unopened
trigonometry book was __________ on the desk. Although final exams were
only two days away, Jacob decided to play another level of Tomb Raider,
his favorite computer game.
The trigonometry book was resting on the desk. Thus, you need a form of lie. Since the sentence has a progressive verb, you need the present participle. You chose the correct form from the table below. Good job!
