Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. call it a day.
Call it a day: This idiomatic expression means to decide to stop working or doing something for the rest of the day, usually because you have done enough or because it's time to quit.
The other options provided do not accurately convey the idiomatic meaning of deciding to finish work or an activity for the day.
Therefore, "call it a day" is the correct choice as it fits the context and meaning of the sentence.
