The best way to complete the sentence is "All the employees were asked to attend the meeting on Saturday." (option D)
Why is "to attend" the best option?
The verb "to ask" is followed by another verb preceded by "to" when it expresses a request. The structure is basically "to be asked to do something." Since letter D is the only option that presents a verb preceded by "to", it is the correct answer:
"All the employees were asked to attend the meeting on Saturday."
